Sodium Hydroxide Uses: Used for science projects, ingredient in homemade soap and wine, Sodium hydroxide is used in themanufactureof pulp and paper, textiles, drinking water, soaps and detergents, and as a drain cleaner.
Sodium Hydroxide Solubility: Highly soluble in water, with a lower solubility in polar solvents such as ethanol and methanol. NaOH is insoluble in ether and other non-polar solvents.
Assuming your 20% is weight on weight, just add 80 grams of water (80 mL at 20 degrees Celsius) to 20 grams of NaOH. You'll have [(20g NaOH) /(20g NaOH+80g water) ]*100 ==> 20g NaOH every 100g of solution.Read more here.
Sodium Hydroxide 20% Solution is used for determining the specific surface area of colladial silicia, also used for the direct oxidation of sodium Borohydride , and used to compose citrate buffer.Read more here.
About Sodium Hydroxide
Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na⁺ and hydroxide anions OH⁻ .
At room temperature,sodium hydroxide is a white crystalline odorless solidthat absorbs moisture from the air. It is a manufactured substance. When dissolved in water or neutralized with acid it liberates substantial heat, which may be sufficient to ignite combustible materials. Sodium hydroxide is very corrosive. It is generally used as a solid or a50% solution. Other common names include caustic soda and lye. Sodium hydroxide is used to manufacture soaps, rayon, paper, explosives, dyestuffs, and petroleum products. It is also used in processing cotton fabric, laundering and bleaching, metal cleaning and processing, oxide coating, electroplating, and electrolytic extracting. It is commonly present in commercial drain and oven cleaners.
Sodium hydroxide is an ingredient in drain and oven cleaners. Sodium hydroxide is used in chemical manufacturing, oil refining, hydraulic fracturing, water treatment and metal processing. Used in the manufacture of fabric, plastic wrap, paper and soap. Sodium hydroxide is used in salt spray testing where pH needs to be regulated. Sodium hydroxide is used to manufacture many everyday products, such as paper and aluminum. Sodium hydroxide has been studied for its use in the treatment of prion disease (as occurs in mad cow disease and kuru).
Sodium hydroxide is very corrosive. It can cause irritation to the eyes, skin, and mucous membrane; an allergic reaction; eye and skin burns; and temporary loss of hair. Workers may be harmed from exposure to sodium hydroxide. Read more here.
Sodium hydroxide has the formula, NaOH and is also known as caustic soda or lye. It is extremely alkali and has a ph of 12. It is one of the strongest alkaline chemicals. It is very caustic and when in contact with the skin, can leave burns.
