Sodium hydroxide is also known as caustic soda, caustic, and lye. Anhydrous (100%, solid) caustic soda has a chemical formula of NaOH and a molecular weight of 40.00. It is available commercially in the form of liquid, solid, flakes, or particles. Sodium hydroxide has diverse industrial applications due to its strong alkaline nature. It is integral to the manufacture of petroleum products, pulp and paper, alumina, textiles, and soaps and detergents, along with its application in chemical processing, water treatment and petroleum processing. For commercial purposes, caustic soda is used either in a 32%, 45% of 50% etc. aqueous solution or as a solid. Industrially, caustic soda is most commonly manufactured by the electrolysis of a sodium chloride (NaCl) solution. The co-products formed from the electrolytic production of caustic soda are chlorine and hydrogen.
