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.[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
edit- Bubbling chlorine through an aqueous suspension of silver oxide.[4]
- 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
Chemical properties
editSilver 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]
