Calcium Hypochlorite quickly forms hypochlorous acid (the killing form of chlorine) in water. It is used in water treatment as a general biocide. Calcium hypochlorite is used by many paper conservationists to bleach archival papers, and it is used as an oxidizing agent to reduce the effects of foxing.
SOLUBILITY RULES Most of the precipitation reactions that we will deal with involve aqueous salt solutions. Remeer salts are compounds which consist of metal ions like Na +, Ca 2+, Cu 2+ (or the one nonmetal molecular ion that we have discussed, ammonium - NH 4 +) ionically bonded to nonmetal anions such as Cl-, (including molecular anions such as hydroxide - OH-, sulfate - SO 4 2
