Bleaching powder is used to sterilize and disinfect water by killing harmful germs and bacteria that can cause diseases. It works by releasing chlorine when mixed with water, following the chemical reaction of CaOCl2 + H2O → Ca(OH)2+Cl2. Bleaching powder sterilizes water through maximum utilization of released chlorine, leaving no impurities and being harmless in minimum amounts, and is a convenient method to kill germs in water.
