Silver hypochlorite is a chemical compound with the chemical formula Ag O Cl (also written as AgClO). It is an ionic compound of silver and the polyatomic ion hypochlorite.^[1]^[2] The compound is very unstable and rapidly decomposes.^[3] It is the silver(I) salt of hypochlorous acid. The salt consists of silver(I) cations (Ag⁺) and hypochlorite anions (⁻OCl).

Synthesis

2 Cl₂ + Ag₂O + H₂O → 2 AgCl + 2 HOCl

2 HOCl + Ag₂O → H₂O + 2 AgOCl

Reaction of hypochlorous acid with silver nitrate produces silver hypochlorite and nitric acid.^[5]

HOCl + AgNO₃ → AgOCl + HNO₃

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.^[3]^{[dubious – discuss]}
