Why is bleaching powder used to disinfect drinking water?

Answer and explanation

Correct answer: It provides chlorine that helps kill germs

Bleaching powder releases available chlorine when it contacts water. This chlorine forms disinfecting species such as hypochlorous acid, which damages essential cell components of many harmful bacteria and other microorganisms. Consequently, it helps make drinking water safer when used in a controlled amount. It is not added to sweeten water, force its pH to zero, or increase salt content.
