Hypochlorous Acid

Chlorine is directly added to the drinking water supplies in the form of gas or calcium hypochlorite or sodium hypochlorite (bleach). The final outcome is a solution which contains hypochlorous acid. This acid finally dissociates to form H+ and OCl- ions. This is very effective in eliminating pathogenic microorganisms as the chemical penetrates their protective membrane.
