Chlorine Chemistry There are three types of chlorine in water: Free Chlorine Combined Chlorine Total Chlorine = HOCl + OCl- = NH2Cl + NHCl2 + NCl3 = Combined Chlorine + Free Chlorine
Free Available Chlorine • Chlorine existing in water as hypochlorous acid (HOCl) or the hypochlorite ion (OCl-) is defined as free available chlorine. The concentration of each is dependant upon the pH of the water being measured. • Strong disinfectant
Total Chlorine • Total Chlorine is a the sum of the combination of the Free Available Chlorine and the Combined Chlorine
