Chlorine are produced for use as disinfectants and bleach for both domestic and industrial purposes, and it is also widely used to disinfect. Chloride is widely distributed in nature, generally as the sodium (NaCl) and potassium (KCl) salts; it constitutes approximately 0.05% of the lithosphere.(1)
By far the greatest amount of chloride found in the environment is in the oceans.Sodium chloride is widely used in the production of
industrial chemicals such as caustic soda (sodium
hydroxide), chlorine, soda ash (sodium carbonate),
sodium chlorite, sodium bicarbonate and sodium
hypochlorite.
