Occurrence, properties, and uses Calcium does not occur naturally in the free state, but compounds of the element are widely distributed. One calcium compound, lime (calcium oxide, CaO) was extensively used by the ancients.The silvery, rather soft, lightweight metal itself was first isolated (1808) by Sir Humphry Davy after distilling mercury from an amalgam formed by electrolyzing a mixture

Chlorine Chemicals used for Water Disinfection
Calcium hypochlorite is more stable than sodium hypochlorite, and contains a higher chlorine concentration (30-75%).The chemical reaction with water is: Ca(OCl)2 + 2H2O <–> 2HOCl + Ca+2 + 2OH- Like sodium hypochlorite, calcium hypochlorite also increases water pH, so it is advised to acidify the water during the disinfection process.
