Hypochlorous acid and hypochlorite ions, when combined, is known as free chlorine. Both of these establish equilibrium and are both temperature and pH dependent at 7.5 pH and 77Â°F (25Â°C). Hypochlorous acid is more potent than hypochlorite ions in terms of disinfection.
Chlorine as chloride (Cl-) is essential for mammals and plants. Digestive juices in the stomache contain hydrochloric acid. Chlorine is never found in nature as the free gas. It is found mainly as rock salt (common salt, halite, NaCl), carnallite (KMgCl3.6H2O), and sylvite (KCl). Density of solid: 2030 kg m-3.
