Products Description of Calcium hypochlorite CAS#7778-54-3

The chemical formula of bleaching powder is CaCl2·Ca(ClO)2·2H2O. It is a white powdery substance. Its composition varies with the preparation conditions. It is generally a hydrated complex salt composed of calcium hypochlorite, calcium chloride and unreacted calcium hydroxide. Its active ingredient is calcium hypochlorite. Bleaching powder has strong oxidizing, corrosive and irritating properties. It can decompose when it comes into contact with water, ethanol or inorganic acid. When it comes into contact with water or inorganic acid, it decomposes into hypochlorous acid. Hypochlorous acid has strong oxidizing, bleaching and bactericidal properties. Therefore, the bleaching effect of bleaching powder is mainly based on the oxidizing property of hypochlorous acid.
