Uses
editBismuth 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.
