Silver hypochlorite is a chemical compound with the chemical formula AgOCl (also written as AgClO). It is an ionic compound of silver and the polyatomic ion hypochlorite. The compound is very unstable and rapidly decomposes. It is the silver(I) salt of hypochlorous acid. The salt consists of silver(I) cations (Ag+) and hypochlorite anions (−OCl).
Properties Silver hypochlorite is very unstable, and its solution will soon disproportionate into silver chlorate and silver chloride:
3 AgOCl → AgClO3 + 2 AgCl If the AgOCl solution is heated to 60 °C, it will rapidly disproportionate. Adding silver oxide stabilizes the solution.
Synthesis Silver hypochlorite can be prepared by bubbling chlorine through an aqueous suspension of silver oxide:
2 Cl2 + Ag2O + H2O → 2 AgCl + 2 HOCl 2 HOCl + Ag2O → H2O + 2 AgOCl It can also be prepared by the reaction of hypochlorous acid with silver nitrate, producing silver hypochlorite and nitric acid.
HOCl + AgNO3 → AgOCl + HNO3
