Antimony sulfate, Sb₂(SO₄)₃, is a hygroscopic material is formed by reacting antimony or its compounds with hot sulfuric acid. It is used in doping of semiconductors and in the production of explosives and fireworks.

Structure

Solid antimony sulfate contains infinite ladders of SO₄ tetrahedra and SbO₃ pyramids sharing corners. It is often described as a mixed oxide, Sb₂O₃.3SO₃.

Chemical properties

Antimony sulfate is sometimes called a "salt" as it can be produced from the reaction of antimony and sulfuric acid, but it should be noted that antimony does not form a nitrate when dissolved in nitric acid, (an oxidising acid) but produces a mixture of antimony oxides, and this contrasts with bismuth which dissolves in both acids to form salts. It is deliquescent, and soluble in acids. It can be prepared by dissolving antimony, antimony trioxide, antimony trisulfide or antimony oxychloride in hot, concentrated sulfuric acid.

2 Sb (s) + 6 H₂SO₄ → Sb₂(SO₄)₃ + 3SO₂ + 6 H₂O

Uses

Owing to its solubility, antimony sulfate has uses in the doping of semiconductors. It is also used for coating anodes in electrolysis and in the production of explosives and fireworks.

Safety

Antimony(III) sulfate causes irritation to the skin and mucous membranes.
