Calcium Hypochlorite 

What is calcium hypochlorite?

Calcium hypochlorite is an inorganic chemical compound. Its formula is CA(OCl)Cl. It is made up of one calcium cation and two hypochlorite anions. Calcium hypochlorite is produced from the chemical reaction between gaseous chlorine and calcium hydroxide. It is usually produced in the form of mineral lime. It is a white solid but commercial samples seem to appear yellow. It stays stable at room temperature but if it is kept in moist air and area it may start to decompose which will result in a strong smell of chlorine.

It is commonly referred to as bleaching powder which is the main active ingredient of commercial products.

History 

In the late 18th century, an industrial process of manufacture of chloride of lime was developed by Charles Tennant and Charles Macintosh. It was discovered in 1799 and was heavily used for disinfecting wounds and trenches during world war I
