sodium polyacrylate and water balanced equation

Invert the beaker over the sink, record observations. A detergent is a surfactant that has cleaning properties in dilute solutions. Metalworking fluids and other industrial lubricants are typically o/w emulsions. His lab has shown that extended surfactants, which are surfactants with intermediate polarity groups (e.g., polypropylene oxide and polyethylene oxide) inserted between the hydrophilic head and hydrophobic tail, are effective in removing these types of oily stains. As it turns out, microemulsification of vegetable oils can reduce viscosity without the need for the transesterification reaction. Sabatini’s lab has developed alcohol-free microemulsions that help remove oil contaminants from the subsurface in an environmentally friendly manner. It's not just major brands like Pampers and Huggies using SAP; it is in ALL of the diapers we tested. “One of our goals is to increase the stability of active compounds that are encapsulated in emulsions in food particles,” says McClements. In contrast, a macroemulsion requires an energy input to reappear. From the stoichiometry of the balanced equation, one mole of benzoic acid reacts with one mole of methanol to give one mole of methylbenzoate assuming 100% reaction. If the balance is tipped in either direction, the emulsifier may lose contact with the phase to which it is less attracted, causing the emulsion to break down. “The latter might be useful if you want to deliver something to the colon or you’re trying to control satiety by getting undigested compounds further down in the gastrointestinal tract.”. These crystals go by several names including hydrogel, sodium polyacrylate, polyacrylate absorbents, or in Pamper's FAQ as Absorbent Gel Material (AGM) and can absorb a significant amount of liquid given their smaller size. The Cc for combinations of emulsifiers is the weighted average for each emulsifier. “Macroemulsion concepts have been around for centuries, but advanced microemulsion concepts are only about two to three decades old,” says Sabatini. Description Marks The water molecules and sodium ions interact through ion-dipole attractions Incorrect Total 1 1 0 (ii) Explain how the polymer sodium polyacrylate can absorb large quantities of water. Complex emulsions, such as microemulsions and multilayer emulsions, promise to further expand the repertoire of applications, particularly in emerging areas such as functional foods and biodiesel production. Eventually, he would like to incorporate nutraceuticals such as these into functional foods. “It’s just that vegetable oil has viscosity problems, especially at lower temperatures.”. “The oil is trapped in the pores because of the interfacial tension between water and oil,” says Sabatini. Prepare five vials of varying numbers of algal balls and hydrogen carbonate indicator, eg one with three balls, one with six, one with nine and so on. Although humans have been making emulsions for hundreds, if not thousands, of years, we are only now beginning to appreciate their diverse applications in many fields. Sodium carbonate is more commonly known as washing soda. NCI Thesaurus (NCIt); DrugBank. The terms surfactant, emulsifier, and detergent are often used interchangeably, but there are distinctions. 2. If you are using sodium bicarbonate for another reason, it may be taken with or without food. “Although guidelines like the HLB scale can help, most of the time experience and experimentation are needed to find the optimal choice of emulsifiers and usage rates.” Neddersen notes that processing can be another challenge when working with food emulsions. Surfactant is the broadest term: Both emulsifiers and detergents are surfactants. Return to the lab table. Explain this. The HLD scale centers on 0, which corresponds to the optimal emulsion. “Time stability points in the direction of microemulsions, but surfactant requirement may point in favor of macroemulsions,” says Sabatini. You can use vegetable oil in a diesel engine, and it’ll work pretty well without modification,” says Sabatini. If a student actually weighed 12.2 g (0.12 mol) benzoic acid and measured 20 mL (15.8 g, 0.49 The reaction produces large quantities of carbon dioxide gas, water and table salt. Dilute to the mark with distilled water. Note colour changes in the indicator solution as the CO2 concentration and the pH change. “If we can lower that interfacial tension with emulsifiers, we can increase our rate of cleaning up contamination.”. Respiration and photosynthesis occur simultaneously in the algal cells. Only the oxygen needs to be balanced. They are tasked with conducting a number of small experiments and observing how the colour changes from yellow/orange to purple when the algal balls and solution are placed under a light source as photosynthesis takes up dissolved CO2 and the pH rises. “You can make them so they’re digested very quickly, like a normal emulsion, or you can make them so they go further down the gastrointestinal tract,” he says. Different types of emulsions could have different applications. Plants metabolise the sugars that form as a result of sunlight, carbon dioxide, and water reacting. “The resulting emulsion has a very high viscosity and low fat content and mimics some of the characteristics of a high-fat product.”. Algal ball photosynthesis kits offer an easier, more accurate method of studying photosynthesis that is perfect for use within the classroom. Method 3: Varying the Number of Algal Balls per Vial. If you are providing students with the already prepared 7mL vials with the algal balls and indicator, it may be a good idea to expose them to light for half an hour or so beforehand to start photosynthesis. If there is no change by the end of the class, your students can come back at the end of the day or the following day to observe the colour change. Today, a wide variety of nature-based and synthetic emulsifiers are available for the diverse fields that benefit from them, including food, nutraceuticals, home and personal care, biofuel, environmental cleanup, and industrial lubricant applications. It is relatively easy to chill the sodium hypochlorite with a chilled water … And we mean all. During the first Match Day celebration of its kind, the UCSF School of Medicine class of 2020 logged onto their computers the morning of Friday, March 20 to be greeted by a video from Catherine Lucey, MD, MACP, Executive Vice Dean and Vice Dean for Medical Education. According to George Smith, technical director for the Americas at Huntsman Performance Products in The Woodlands, Texas, USA, a combination of emulsifiers usually works better than any single emulsifier. “If you’re trying to make a mineral oil emulsion, for example, the HLB for mineral oil is 10,” he says. a) Give the monomers involved in glyptal in a stoichiometric chemical reaction equation. AOCS Headquarters 2710 S. BoulderUrbana, IL 61802-6996 USA Phone: +1 217-359-2344 Fax: +1 217-351-8091, AOCS Mailing AddressP.O. Non-genetically modified soy is expensive and in short supply. “The trend right now is most people would like to use an emulsifier that’s based on plant raw materials rather than petrochemicals,” says Smith. Ethoxylated alcohols are a common ingredient of laundry detergents. “The price swings back and forth depending on the price of palm kernel oil in Malaysia and the price of ethylene in North America,” says Smith. READ PAPER. HCl, or hydrochloric acid, is a strong acid that reacts with sodium carbonate. For Experiment 1, provide students with one vial of twelve balls which has already been exposed to light. In the 1970s, the hydrophilic-lipophilic difference (HLD) system was introduced. Milk is an example of an o/w emulsion, in which the fat phase or cream forms tiny droplets within the skim milk, or water phase. However, “It’s too early to say that ethoxylated alcohols can be replaced,” says Mateu. “There are some emulsions you can make with glucosides, but for the most part the whole world is still using ethoxylates.”. The emulsifier is typically electrically charged, and the polymer layer(s) have opposite charges that attract them to the surface of the oil droplet. Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain. Because microemulsions are a thermodynamically stable end point that a system naturally migrates toward, they generally do not require vigorous mixing. Different emulsifiers have different HLB values, which can predict their ability to stabilize various kinds of emulsions (Fig. As a strong base, sodium hydroxide neutralizes gastric acid thereby acting as an antacid. Cabloc is based on cross-linked sodium polyacrylate, Creasorb on cross-linked acrylamide/acrylic acid potassium salt, and Hydropam on sodium salt and acrylamide/acrylic acid copolymer. Use a plastic pipette to add 3mL of hydrogen carbonate indicator to each vial. Reduced-fat emulsions are another hot topic for the food industry. The HLB scale ranges from 0 to 20, with 10 corresponding to an emulsifier that is equally attracted to water and oil. “Aesthetically, the product is the same thing—it feels the same and looks the same—so why not?” he says. (b) two on the left. “There’s growing interest in microemulsions because we’re just beginning to understand their capabilities.”. Sodium Carbonate is the disodium salt of carbonic acid with alkalinizing property. Exciton migration to emissive defects in π-conjugated polymers is a robust signal amplification strategy for optoelectronic sensors. The HLD equation includes terms for the salt concentration, “oiliness” of the oil (the effective alkane carbon number), and the characteristic curvature (Cc) of the emulsifier. For example, when oil or gas is spilled, the oil becomes trapped in pores in the soil and rock. “You could take some of the fat out of the droplets and replace it with water,” he says. Egg yolk, the traditional emulsifier for mayonnaise and sauces, also contains lecithin. I can calculate the number of grams of a reactant or product in a balanced chemical equation when given the number of grams of another reactant or product. Compared to macroemulsions, microemulsions require more surfactant. Observe any colour changes in both vials. b) What solvent is used to make glyptal? The secret ingredients in Jeesperse products are polyelectrolytes, such as sodium polyacrylate. Making food emulsions can be challenging because “foods are complex systems with many different ingredients interacting,” says John Neddersen, senior application scientist in fats, oils, and emulsifiers at DuPont Nutrition and Health, based in New Century, Kansas, USA. In eukaryotic cells, specialised organelles facilitate biochemical processes of photosynthesis, cellular respiration, the synthesis of complex molecules (including carbohydrates, proteins, lipids and other biomacromolecules), and the removal of cellular products and wastes (ACSBL049). , Which is the equation we seek to determine the mass of M 2+ absorbed by sodium polyacrylate for Experiment 2 (subject of LA 11). “At the moment, I think petrochemicals have the advantage, but it switches every two to three years.”, Juan Mateu, technical director at JEEN International in Fairfield, New Jersey, USA, says that there has been a move away from synthetic ethoxylated alcohols in recent years due to worries about residual 1,4-dioxane, a suspected carcinogen that is a by-product in their manufacture. Emulsions and microemulsions have been applied to environmental technologies such as subsurface remediation and biofuel production. There is an equal number of each element on both sides of the equation. (Draw the structure and give the number of these monomers involved in a stoichiometrically balanced reaction.) Examples include a gas station with a leaky underground tank and a military site contaminated with jet fuel. The Centers for Disease Control explains that when you mix sodium hydroxide with water or acid, the reaction is so exothermic that nearby combustible materials may ignite 3 . Start your journey today The type of emulsifier used depends on the application, with cationic emulsifiers typically used in low-to-neutral pH solutions and anionic emulsifiers in alkaline solutions. This emulsifier can substitute for soy lecithin, which has recently come under fire, particularly in Europe, because most soy crops grown for export (especially the United States, Brazil, and Argentina) are genetically modified. Online calculators exist to optimize the HLD for a particular emulsion (e.g., www.stevenabbott.co.uk/HLD-NAC.html). Position this vial near a light source, but do not expose it to too much heat. c) The swelling ratio Q for the hydrogel was about 100 to 500. Varying the number of algal balls and light intensity gives students the opportunity to explore the effect on algae. It has the ability to absorb as much as 300 times its mass in water. Many household cleaners and laundry detergents contain surfactants that emulsify oily dirt particles so that they can be diluted and washed away. Procedure: Measure one small scoop of sodium polyacrylate into a beaker (100, 150, or 250 mL). In the safety aspect, it’s non-toxic, non-pollutant, and harmless. Academia.edu is a platform for academics to share research papers. Sodium hydroxide and calcium hydroxide have important differences 4. Detailed parameters of TiO 2 nanoparticles are shown in Table 1.Molecular weight of sodium polyacrylate is 2100. Next, pour the rinse liquid into the second vial and repeat until you have rinsed all required vials. Add a small amount of distilled water, swirl to dissolve the salt and then dilute to the mark with distilled water. A foam is a substance in which gas bubbles are suspended in a liquid. “But time is not a factor in how long a microemulsion will remain in its current state.” In addition, if a temperature change causes an emulsion to break down, a microemulsion will spontaneously reform when the temperature changes back to its original value. The HLB system, which works primarily for non-ionic emulsifiers, has been around since 1954. In both cases, emulsifiers are needed to prevent the suspended droplets from coalescing and breaking the emulsion. Place twelve balls in each vial and place the vials at varying measured distances from a light source. Algal balls are stored in small vials filled with hydrogen carbonate indicator solution. In this way, emulsifiers lower the interfacial tension between the oil and water phases, stabilizing the droplets and preventing them from coalescing. Vials are stored in the dark for a short period to observe the colour change from purple to yellow/orange as respiration occurs and the pH falls. How do product formulators choose which emulsifier to use for a particular emulsion? A. Reversible and Irreversible Reactions Questions on Video 1: Chemical Reaction between Sugar and Sulfuric Acid [2.5 points] 1. As the name suggests, microemulsions have smaller droplet sizes than regular emulsions, making them appear transparent rather than opaque. Laura Cassiday is a freelance science writer and editor based in Hudson, Colorado, USA. As a result of the lowered CO2 levels, the pH of the solution will rise. By 2015, DuPont has pledged to source 100% of its palm oil from plantations certified by the Roundtable on Sustainable Palm Oil (RSPO). The cell membrane separates the cell from its surroundings and controls the exchange of materials, including gases, nutrients and wastes, between the cell and its environment (ACSBL045). AOCS Mailing Address P.O. ||Biology||Classroom Practicals||Cells||Year 11 & 12||. Prepare five vials of algal balls and hydrogen carbonate indicator. “In terms of combustion, you don’t need to modify the vegetable oil. Emulsifiers coat droplets within an emulsion and prevent them from coming together, or coalescing. c) Draw the structure of sodium acetate and explain why it was used in this reaction. As more light becomes available, photosynthesis dominates. Many detergents contain a blend of nonionic and anionic emulsifiers to lift stains out of textiles. ... Why are water molecules pulled into a polymer. When dissolved in water, sodium carbonate forms carbonic acid and sodium hydroxide. In this practical, students have the opportunity to tangibly observe photosynthesis. When charged emulsifiers coat droplets in an o/w emulsion, the positive or negative charges on the outside of the oil droplets electrostatically repel each other, helping to keep the droplets separated. Sodium polyacrylate is widely used in disposable diapers. During photosynthesis, radiant energy is converted into organic substances that can be stored within the plant to support growth, reproduction, and metabolism. Biodiesel is a vegetable oil, such as soybean oil, that has been chemically modified through a transesterification reaction to reduce its viscosity. The session, which will be held on Wednesday, May 7, from 1:55–5 p.m., will feature a wide range of technical topics—from the fabrication of reduced-fat products by controlled aggregation of lipid droplets to the formulation of lipopeptide biosurfactant mixtures for dispersing oil spills in seawater. Therefore, emulsifiers are attracted to both polar and nonpolar compounds. The resulting product appears very similar to fake snow, as you mentioned, a solidified powder like substance. Monday, September 19, 2016. In contrast, margarine is a w/o emulsion containing droplets of water or skim milk in a blend of vegetable oils and fat. compound (water) causes the reaction to occur and is the source of the heat given off. The preparation process of aqueous suspension is as follows: 1 g is added to the 200 mL deionized water, which aims to prevent the aggregation of nano … Headspace gas chromatography connected to an FID and/or an MS detector can be applied to obtain better precision and accuracy for the quantitative analysis of volatile organic compounds (VOCs) in bio-oils including light aldehydes and ketones, ethers, esters, alcohols, carboxylic acids and aromatic compounds [32,49]. They are tasked with conducting a number of small experiments and observing how the colour changes from yellow/orange to purple when the algal balls and solution are placed under a light source as photosynthesis takes up dissolved CO. and the pH rises. Prepare two vials of twelve algal balls and hydrogen carbonate indicator. Increasingly, formulators are interested in making microemulsions, which offer greater stability than conventional macroemulsions. b) What happened when uncrosslinked polyacrylate was added to water? By matching the HLB value of the emulsifier with that of the oil, formulators can greatly increase their chances of producing a stable emulsion. Add 10 mL of water. This is a great practical to introduce students to the basic principles of photosynthesis in a fun, simple and interactive way. *This page is about the good water-absorbing material – Sodium polyacrylate uses. When no light is available, respiration will dominate and the pH will decrease through the release of CO. Changes in the levels of carbonic acid can be monitored via the colour changes that occur due to the hydrogen carbonate indicator. Non-ionic emulsifiers tend to have large, bulky head groups that point away from the oil droplet. Milk is an example of an o/w emulsion, in which the fat phase or cream forms tiny droplets within the skim milk, or water phase. Anybody who has made a simple oil-and-vinegar salad dressing knows that, with enough shaking or whisking, one can make a temporary emulsion. Property Name Property Value Reference; Molecular Weight: 381.4: Computed by PubChem 2.1 (PubChem release 2021.05.07) Hydrogen Bond Donor Count: 10: Computed by Cactvs 3.4.6.11 (PubChem release 2019.06.18) Divide the correct number of algal balls into each vial. Storage of sodium hypochlorite at approximately 60°F (15°C) will greatly reduce the decomposition of the sodium hypochlorite. Reliably studying photosynthesis first hand can be difficult and require precise setting up. Write the balanced equation for the reaction of methanoic acid with ethanol. Sodium polyacrylate also referred to as Slush Polymer with the chemical formula [−CH 2 −CH(CO 2 Na)−] n. It has the capacity to absorb and retain … This is a great practical to introduce students to the basic principles of photosynthesis in a fun, simple and interactive way. However, as conditions become darker, photosynthesis is retarded and respiration takes over as the main process. Plants metabolise the sugars that form as a result of sunlight, carbon dioxide, and water reacting. Know and follow all regulatory guidelines for the disposal of laboratory wastes. Most personal care products, including lotions, creams, shampoos, and conditioners, are emulsions. A short video demonstrating the cold-process formulation of a lotion with a Jeesperse emulsifier. how formulators choose which emulsifier to use for a particular emulsion; how emulsifiers are used in foods, nutraceuticals, personal and home care products, industrial lubricants, environmental technologies, biofuels, and other applications. Reliably studying photosynthesis first hand can be difficult and require precise setting up. Prepare another vial of twelve algal balls and hydrogen carbonate indicator. For example, a very hydrophilic emulsifier, sodium laurel sulfate, has a Cc of –2.3, whereas a very hydrophobic emulsifier, dioctyl sodium sulfosuccinate, has a Cc of 2.6. I can identify the quantitative (mass) relationship in a balanced chemical equation and relate to conservation of mass. Wrap a piece of coloured transparent film around each vial and position near a light source, but do not expose them to too much heat. Sustainable sourcing of palm oil has also become a customer concern, as reports have surfaced that the development of palm oil plantations harms the environment and threatens endangered wildlife in Malaysia and Indonesia, where most palm oil originates. C. The law of conservation of mass has already been applied. CuO + HNO3 = Cu(NO3)2 + H2O. why isn’t PMMA a superabsorbent? Therefore, cooling the product before shipment will greatly reduce its decomposition. As an alternative to lecithin in chocolates and other confectionary, DuPont offers Grindsted® CITREM, a citric acid ester. I am trying to do a small scale (approximately 20 micromol of azide and 50 micromol of alkyne) click reaction using CuSO4.5H2O (5-10 mol%) and (+) sodium -L-ascorbate (20 mol%). In contrast, Jeesperse allows the emulsion to be made in a single kettle at room temperature, resulting in significant savings of money and time. Photosynthesis is a biochemical process that in plant cells occurs in the chloroplast and that uses light energy to synthesise organic compounds; the overall process can be represented as a balanced chemical equation (ACSBL052), During photosynthesis, radiant energy is converted into organic substances that can be stored within the plant to support growth, reproduction, and metabolism. There are equal numbers of hydrogen and carbon. In 1997, Sabatini and several colleagues founded a company called Surbec Environmental, LLC, to implement this technology. Researchers are exploring emulsions as delivery vehicles for vitamins, supplements, and other nutraceuticals. However, formulators often use gentle agitation to evenly spread the components and speed up the process of microemulsion formation. McClements’ lab has used emulsions to encapsulate vitamin E, carotenoids, omega-3 fatty acids, curcumin, coenzyme Q10, and other bioactive compounds. (SiO 2) y, such as sodium metasilicate Na 2 SiO 3, sodium orthosilicate Na 4 SiO 4, and sodium pyrosilicate Na 6 Si 2 O 7.The anions are often polymeric.These compounds are generally colorless transparent solids or white powders, and soluble in water in various amounts. “Given enough time, a macroemulsion will break down into water and oil phases,” says David Sabatini, associate director of the Institute for Applied Surfactant Research at the University of Oklahoma, Norman, USA. Non-ionic emulsifiers can be used alone or in combination with charged emulsifiers to increase emulsion stability. Collect your vial of twelve algal balls which has already been exposed to light. When no light is available, respiration will dominate and the pH will decrease through the release of CO2. Balanced Chemical Equation For Respiration In Plants 2). It contains branches that connects polymer chains. If you do not plan to use it immediately, store in a cool place away from direct sunlight and areas of high heat. B. For the reaction between permanganate ion and sufite ion in basic solution, the unbalanced equation is: MnO 4-+ SO 3 2-MnO 2 + SO 4 2-When this equation is balanced using the smallest whole number coefficients possible, the number of OH-ions is (a) two on the right. Surfactants, or surface-active agents, are compounds that lower the surface tension between two liquids or between a liquid and a solid. Box 17190Urbana, IL 61803-7190 USA, © 2021 The American Oil Chemists' Society, Plant Protein Science and Technology Forum, Soybean 360: Agro Processing in Sub-Saharan Africa. After reading this article, you will understand: The immiscibility of oil and water has inspired the proverb “Oil and water don’t mix” and other expressions that reflect the general incompatibility of two entities, such as “My coworker and I are like oil and water.” Yet within our homes are numerous examples of products in which oil and water do mix: mayonnaise, milk, salad dressings, hand lotion, and hair conditioner, to name but a few. Technical session highlights suspensions, emulsions, and foamsYou can learn about the latest developments in suspensions, emulsions, and foams by attending a joint technical session on these topics at the upcoming 2014 AOCS Annual Meeting & Expo in San Antonio, Texas, USA. “A company might have a single formula run at multiple locations and see different results at the different plants,” he says. Macroemulsions require high-intensity mixing. Likewise, the terms emulsion, suspension, and foam are sometimes confused. If you have enough algal balls and cellophane, you can try the whole rainbow! Cationic emulsifiers are rarely used because they are unstable in the alkaline solutions (pH 8–9.5) required for metalworking fluids. “It may be that 3 or 6 months is plenty long enough for your application and time may not be a factor in that situation.” For example, food products will often go bad before a macroemulsion breaks down, he says. An emulsifier is a surfactant that stabilizes emulsions. Take sodium bicarbonate exactly as directed. beaker several times with distilled water and pour that solution into the volumetric flask. After placing the vial in the dark, you should observe the colour in the vial change from purple to yellow/orange as respiration occurs and the pH falls. However, in the absence of emulsifiers, this unstable emulsion breaks down within minutes, and the oil forms a layer on top of the vinegar. A type of surfactant (see Sidebar), emulsifiers contain both a hydrophilic (water-loving, or polar) head group and a hydrophobic (oil-loving, or nonpolar) tail. DuPont sells a broad range of emulsifiers, including the Panodan® DATEM (diacetyl tartaric acid ester of monoglycerides) line especially for bakery products and the Cremodan® line for ice creams and other frozen desserts. (c) three on the right. In contrast, emulsifiers with HLB values less than 10 are more hydrophobic and therefore better suited for w/o emulsions. Used SAPs differ mainly in terms of solubility, while Cabloc and Creasorb do not dissolve in water, Hydropam is slightly soluble and creates a gel. The particles are large enough for sedimentation. Multilayer emulsions consist of oil droplets coated with an emulsifier plus one or more biopolymer layers, dispersed in an aqueous solution. Sodium polyacrylate. Emulsifiers can be cationic (positively charged polar head group), anionic (negatively charged head group), or non-ionic (uncharged head group). Mateu says that in the lab, he can make an emulsion with the cold process in about 20 minutes, as opposed to several hours of mixing, heating, and cooling with the conventional process. The equation needs to be balanced. Copper sulfate is a blue solid (it exists as the pentahydrate) and readily dissolves in water to make a blue solution containing Cu2+ ions and SO4^2- ions. “So you have to have a different kind of delivery system for each application.”. As a result of the lowered CO. levels, the pH of the solution will rise. The vial should be exposed to light long enough for it to turn purple or near purple on the colour spectrum. Some change should be expected by the end of the class, however if it is too slight to notice you can return at the end of the day or the next day to check your vials. For example, sodium polyacrylate is a polyelectrolyte SAP and swells due to osmotic pressure effects. D. Julian McClements, professor of physico-chemistry at the University of Massachusetts Amherst, USA, says that there are several ways that emulsions or emulsifiers could help reduce the fat content of foods. These examples represent emulsions, which are stable mixtures of tiny droplets of one immiscible fluid within another, made possible by chemicals called emulsifiers. “We’d also like to control their fate in the gastrointestinal tract once they’ve been digested.”, In addition to conventional emulsions, McClements’ lab makes more complex emulsions such as nanoemulsions, solid-lipid nanoparticles, filled hydrogel particles (Fig. Write a balanced equation for reaction of copper (II) oxide. Sodium carbonate is a white solid and dissolves in water to make Na+ ions and CO3^2- ions. When exposed to light, the encapsulated algae absorb the CO, from the solution they are stored in during the process of photosynthesis. The cross-links that connect the chains together prevent them from dissolving/breaking apart in the water. Sodium polyacrylate, also known as waterlock, is a sodium salt of polyacrylic acid with the chemical formula [-CH2-CH(CO2Na)-]nand broad application in consumer products.
