Calcium hypochlorite is a chemical compound with formula Ca(ClO)2. It is widely used for water treatment and as a bleaching agent. This chemical is considered to be relatively stable and has greater available chlorine than sodium hypochlorite.

Formula: Ca(ClO)2, IUPAC ID: Calcium dihypochlorite, Molar mass: 142.98 g/mol, Density: 2.35 g/cm³, Melting point: 100 °C, Boiling point: 175 °C, Soluble in: Water

Uses

Calcium hypochlorite is used for the disinfection of drinking water or swimming pool water. Generally it is sold as 68% calcium hypochlorite combined with calcium chloride and other salts. It is used as a sanitizer in outdoor swimming pools in combination with a cyanuric acid stabilizer, which reduces the loss of chlorine due to ultraviolet radiation. The calcium content hardens the water and tends to clog up some filters; hence, some products containing calcium hypochlorite also contain anti-scaling agents.

Calcium hypochlorite is an ingredient in bleaching powder, used for bleaching cotton and linen. It is used in bathroom cleaners, household disinfectant sprays, moss and algae removers, and weedkillers.

In addition, calcium hypochlorite may be used to manufacture chloroform.

Bleaching powder is used in the sugar industry for bleaching sugar cane juice before its crystallization.
