【Summary】The chemical formula of calcium hypochlorite is Ca(OCl)2, a calcium hypochlorite molecule contains 2 hypochlorite radicals, the relative molecular mass = 143; the chemical formula of sodium hypochlorite is NaOCl, a sodium hypochlorite molecule contains 1 hypochlorite radical, and the relative molecular mass = 74.5. Therefore, the content of hypochlorite in the same quality of calcium hypochlorite and sodium hypochlorite, calcium hypochlorite is more, and the bleaching property of calcium hypochlorite is greater than that of sodium hypochlorite.

Therefore, the content of hypochlorite in the same quality of calcium hypochlorite and sodium hypochlorite, calcium hypochlorite is more, and the bleaching property of calcium hypochlorite is greater than that of sodium hypochlorite.

 

Extended information: Bleaching powder is an oxidative bleaching agent. The principle is that the active ingredient of bleaching powder, calcium hypochlorite, reacts with carbon dioxide to generate hypochlorous acid. Hypochlorous acid is very oxidizing and destroys the "chromophore" of organic colors. This bleaching process is irreversible, and substances bleached with bleach cannot restore their original color. The bleaching principle of bleaching powder shows the bleaching function through the strong oxidizing property of the generated hypochlorous acid, and has a strong bactericidal function at the same time
