Antimonite

This article is about the class of chemical salts. For the mineral, see stibnite.

In chemistry, antimonite refers to a salt of antimony(III), such as NaSb(OH)4 and NaSbO2 (meta-antimonite), which can be prepared by reacting alkali with antimony trioxide, Sb2O3.[1] These are formally salts of antimonous acid,[2] Sb(OH)3, whose existence in solution is dubious. Attempts to isolate it generally form Sb2O3·xH2O, antimony(III) oxide hydrate, which slowly transforms into Sb2O3.[1]

In geology, the mineral stibnite, Sb2S3, is sometimes called antimonite.

Antimonites can be compared to antimonates, which contain antimony in the +5 oxidation state.
