Chlorine Water

 

an aqueous solution of chlorine. Chlorine water is obtained in a chlorinator by saturating water with chlorine (one volume of water will dissolve about 2.2 volumes of chlorine gas at 20°C). As chlorine water cools, chlorine hydrate is precipitated out—a compound of variable composition, Cl2 · nH2O (where n = 6 to 8)—in the form of yellow crystals, which melt with decomposition at 9.6°C. At ordinary temperatures, up to 50 percent of the chlorine dissolved in chlorine water undergoes hydrolysis: Cl2 + H2O ⇄ HClO + HCl. The HClO thus formed is decomposed by light to O2 and HCl. Chlorine water is a strong oxidizing agent. It is used for water disinfection and for bleaching fabrics.
