Antimonous acid is unknown, but the conjugate base sodium antimonite () forms upon fusing sodium oxide and .Wiberg and Holleman, p. 763 Transition metal antimonites are also known. Antimonic acid exists only as the hydrate , forming salts as the antimonate anion . When a solution containing this anion is dehydrated, the precipitate contains mixed oxides.
