Silver chlorate

Chemical compound From Wikipedia, the free encyclopedia

Silver chlorate is an inorganic compound with molecular formula AgClO3. It exists in two forms: white tetragonal prisms, and cubic crystals.[3][2][4] Like all chlorates, it is water-soluble and an oxidizing agent. It is light-sensitive, so it must be stored in tightly closed dark-coloured containers.[5]

Production

Silver chlorate is produced by the reaction of silver nitrate with sodium chlorate to produce both silver chlorate and sodium nitrate:[5]

AgNO3 + NaClO3 → AgClO3 + NaNO3

Alternatively, it may be produced by the bubbling of chlorine gas through a suspension of silver oxide (Ag2O), or by dissolving Ag2O or metallic silver in chloric acid.[2]

Safety

Aside from the potential dangers associated with strong oxidizers, silver chlorate may cause argyria, eye irritation, skin irritation, and temporary respiratory issues.[6]

It also has the potential to explode when heated very rapidly, or if exposed to ammonia which may form the explosive complex triamminesilver chlorate (AgClO3·3NH3).[2]
