Decomposition of Calcium Hypochlorite

2Ca(OCl)2 → 2CaCl2 + O2

概述

Calcium hypochlorite slowly decomposes to release oxygen, which is why it has strong oxidizing and bleaching properties. The decomposition rate increases with temperature and moisture. This is the active ingredient in many pool chlorination products.
