Bismuth hydroxide (Bi(OH)
3) is non-fully characterised chemical compound of bismuth. It is produced as white flakes when alkali is added to a solution of a bismuth salt and is usually described as bismuth oxide hydrate[1] or bismuth hydrate.[2]

Uses

Bismuth hydrate is a component used in milk of bismuth[3] which is used in gastrointestinal disorders as a protective agent.[4] Aqueous ammonia reacts with bismuth(III) ions to precipitate white bismuth hydroxide.[5]

It is used as an absorbent, and in the hydrolysis of ribonucleic acid. It is also used in the isolation of plutonium from irradiated uranium.
