Calcium hypochlorite reacts with hydrochloric acid, yielding calcium chloride (CaCl 2), water, and chlorine gas (Cl 2). The chemical equation for this reaction is 4HCl + Ca(ClO) 2 → CaCl 2 + Cl 2 + H 2 O; What are the Uses of Calcium Hypochlorite? The compound Ca(ClO) 2 is often used to disinfect large volumes of water in order to make it safe to drink.
