Description
In chemistry, antimonite refers to salts of antimony(III), such as NaSb(OH)4 and NaSbO2 (metaantimonite) that can be prepared by the reaction of alkali with antimony trioxide, Sb2O3. [1] These are formally salts of antimonous acid (antimonious acid[2]), "Sb(OH)3" whose existence in solution is doubtful, and attempts to isolate them generally form Sb2O3.xH2O, antimony(III) oxide hydrate, which slowly metamorphoses to Sb2O3. [1] In geology, the mineral stibnite, Sb2S3, is sometimes called antimonite. They can be compared to antimonates, which contain antimony in the +5 oxidation state.
