Description
A fine white powder that is a strong oxidizing bleach. Calcium chloride hypochlorite is prepared by passing chlorine gas through slaked lime. It decomposes in water to produce chlorine. Some commercial bleaching powders are prepared as physical mixtures of Calcium chloride and Calcium hypochlorite. Aqueous solutions of calcium chloride hypochlorite are equivalent to solutions of calcium hypochlorite with Calcium hydroxide. Both contain about 60-65% available chlorine.
