Description and Uses
Sodium hypochlorite is marketed only as an aqueous solution because the anhydrous solid is highly unstable and can explode. The solid pentahydrate also is unstable in air, decomposed by reaction with carbon dioxide from air. Aqueous solutions are very stable. They are used for bleaching textiles and paper pulp; in cleaning solutions; in water purification; as a disinfectant for swimming pools; and as a germicide and topical antiinfective. The hypochlorite also is used as an oxidizing agent in many preparative reactions. It is an ingredient of commercial bleaching products such as Clorox and Dazzle.
