Where do we get sodium polyacrylate at home other than diapers?
Sold in garden supply stores to be mixed into soil to help it retain moisture.Disposable diapers would be the most common consumer use, though.
What is sodium Polyacrylate? how can i find it?
Sodium polyacrylate also named acrylic sodium salt polymer or simply ASAP (repeating unit: -CH2-CH(COONa)- ) is a broad category of polymer chemistry. The crystals are probably coming from the "super absorbent layer" found in most disposable diapers. This layer consists of paper fluff and a chemical absorbent called sodium polyacrylate. Sodium polyacrylate is an amazing water absorber -- it can absorb 200 to 300 times its weight in tap water (even more if the water is distilled) and hold it in a gooey gel. Sodium polyacrylate is a polymer, meaning that it consists of chains of identical units (monomers). The monomer for sodium polyacrylate is: --CH2--CH(CO2Na)-- It is a pretty cool polymer -- shake the crystals out of a new diaper (or buy the crystals at a garden center) and add water to them. Pretty amazing! There is concern in certain circles about the use of sodium polyacrylate next to a child's skin. The concern is often used as an argument against disposable diapers. In addition to its use in disposable diapers, sodium polyacrylate, have many uses. It is found in soil to help soil retain water. It is used by florists as a dirt-free way to store water and to keep cut flowers fresh for a long time. It is used in filtration units that remove water from airplane and automobile fuels such that vehicles perform more efficiently. It is used to make Gro-Creatures, which are toys shaped like dinosaurs, fish, lizards, and other assorted animals that increase in size when placed in water. These critters can be dried out and rehydrated over and over again who have alllergies, especially allergy to disposable diapers should be an observer or recorder for the group. Sodium polyacrylate is non-toxic! However, if placed in the eye, the eye will become dry and irritated. Inhalation of the powder will also be irritating to nasal membranes. Be careful, and minimize exposure to sodium polyacrylate. Dispose of excess powder and/or gelled material in the trash. Do not put down the sink...
What products contain sodium polyacrylate?
Sodium polyacrylate, or waterlock as it is commonly known, is a polymer of polyacrylic acid. It is a widely used super-absorbing polymer. As the name ‘waterlock’ suggests, the compound has the ability to absorb several hundred times of its mass in water as well as other liquid mixtures. It is not a naturally-occurring polymer and is manufactured synthetically. It is widely used in consumer products and in the industrial sector as a binding agent, emulsion stabilizer, film former, and viscosity-controlling agent.It was first developed by National Aeronautics and Space Administration (NASA) about 50 years ago and was used in diapers that astronauts could wear while they were on long space trips. Since then, several other uses of the polymer have been discovered. For example, agriculture grade sodium polyacrylate is used to water the plants in an efficient manner. When plants need water, their roots move closer to the polymer and absorb water from it. Sodium polyacrylate is commonly used in sanitary products such as baby diapers and pet pads. It is employed as a thickening agent in consumer products such as hair gels, upholstery, carpets, and paints.While sodium polyacrylate has several advantages, there are also a few limitations associated with the polymer. For example, it can be highly toxic when inhaled or ingested. It can also cause mild irritation to skin, eyes, and respiratory tract. In 1985, use of sodium polyacrylate in tampons was stopped, as it caused unacceptable levels of irritation to women. However, in total, advantages of the polymer significantly outweigh its drawbacks.Various industries wherein sodium polyacrylate is used (for example, medical, sanitary, agriculture, consumer products, coatings, building materials, and electrical), are expanding at a significant rate. Due to this, the global sodium polyacrylate market has also been expanding at a significant pace. The trend is expected to continue in the next few years. Apart from these existing markets and industries, one of the driving factors behind this growth will be that, even though the polymer has been around for a long time, new applications in new industries are continuously being developed. Accordingly, the market can be segmented by end-user industries.A sample of this report is available upon request @ Sodium Polyacrylate Market
What happens when sodium is in water?
We all are well known with the fact that sodium is kept/preserved in kerosene so as to avoid its direct contact with the air.This is due to the high reactivity of Na metal in the air.Sodium is a soft metal and we can easily cut it with a knife. Sodium gives out a vigorous reaction when comes in contact with humidity/water molecules.The reaction is:[math]2Na+2H_2O →2NaOH+H_2[/math]When sodium reacts with water, sodium hydroxide is formed hydrogen gas as a byproduct that gets burnt with a bright flame….making the reaction highly exothermic.The solution formed after the reaction is basic in nature due to the dissolution of NaOH in water.This is what happens when Na is reacted with water:Thank you!!
What are some common uses of sodium chlorite?
It can be used as:A bleaching agent (generates chlorine dioxide) - mainly in the textile & paper industries, but also in low concentrations in mouthwashes, toothpastes & eye drops.As a disinfectant (in water treatment plants, on food preparation surfaces or in contact lens cleaning solutions).A chemical reagent (e.g in the Pinnick oxidation of aldehydes to carboxylic acids).As a powerful oxidant, it is toxic in concentrations above 1 mg/L, with a 10–15g dose proving fatal if ingested. Suitable precautions must therefore be taken if used for bleaching or disinfectant purposes.
Is sodium acetate, in an aqueous solution, basic?
NaCH3COO(s) --> Na+(aq) + CH3COO-(aq)CH3COO-(aq) + H2O(l) --> CH3COOH(aq) + OH-The equation clearly states it is basic (slightly), but the equation does not look quite complete. I will explain why about the new products:CH3COOH + OH- . Since the new product CH3COOH itself still undergoes dissociation slightly into CH3COO- AND H+ with water molecules. It should reduce OH- concentration slightly cuz the oh- concentration from sodium acetate is still lots larger than h+ ions concentration produced from acetate.
I know that Sodium polyacrylate is found at Garden stores but what is it called there?
It is called ASAP but not all garden centers may have it. You can take the same crystals out of an unused disposable diaper. Be careful you don't breathe them in or get them in your eye because it doesn't distinguish between water or bodily fluids. To me the benefits are not worth the risk
