When mixed with water, chlorine gas forms hypochlorous acid, the primary chlorine-based disinfecting agent, hypochlorite ion, and hydrochloric acid. These alkali metals are found everywhere in nature, especially in the earths crust. Chlorine is the most common disinfectant in water treatment for both primary and secondary disinfection. It is typically used in one of three forms: (1) chlorine gas under pressure, which is dissolved in water at the point of application; (2) a solution of sodium hypochlorite; and (3) solid calcium hypochlorite (U.S. EPA, 1999b). Potable water treatment plants sometimes use groundwater as a source, and this water may contain many milligrams per liter (mg/L) of dissolved calcium and magnesium. PERCENT BY MASS. Question 7.
