Overview of Calcium Hypochlorite
 Calcium hypochlorite is a chemical compound with formula Ca(ClO)2. Calcium hypochlorite is widely used for water treatment and as a bleaching agent (bleaching powder). Calcium hypochlorite is considered to be relatively stable and has greater available chlorine than sodium hypochlorite.Calcium hypochlorite is a yellow white solid which has a strong smell of chlorine. It is not highly soluble in water, and is more preferably used in soft to medium-hard water. It has two forms: a dry form and a hydrated form. The hydrated form is safer to handle.
Calcium hypochlorite reacts with carbon dioxide to form calcium carbonate and release chlorine:
2 Ca(ClO)2 + 2 CO2 → 2 CaCO3 + 2 Cl2 + O2
Calcium hypochlorite reacts with hydrochloric acid to form calcium chloride:
Ca(ClO)2 + 4 HCl → CaCl2 + 2 H2O + 2 Cl2

Usage of Calcium Hypochlorite
Calcium hypochlorite is used for the disinfection of drinking water or swimming pool water. 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 also an ingredient in bleaching powder, used for bleaching cotton and linen. It is also 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 also in sugar industry for bleaching sugar cane juice before its crystallization.
