Antimony sulfate, Sb2(SO4)3, is a hygroscopic salt 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. [4]
Structure
Antimony(III) sulfate consists of interconnected SbO6 octahedra, which the corners are bonded to the sulfate ion. [1]
Production
Antimony(III) sulfate was first produced in 1827 by the reaction of antimony(III) oxide and 18 molar sulfuric acid at 200 °C: [1]
- Sb2O3 + 3 H2SO4 → Sb2(SO4)3 + 3 H2O
The concentration of the sulfuric acid is important, as a lower concentration will produce basic antimony oxides, while a higher concentration will produce antimony(III) pyrosulfate. The reaction of elemental antimony and 18 M sulfuric acid will also produce antimony(III) sulfate: [4]
- 2 Sb + 6 H2SO4 → Sb2(SO4)3 + 3 SO2 + 6 H2O
Chemical properties
Antimony sulfate is deliquescent, hydrolyzing in moist air and water, producing various basic antimony oxides and antimony(III) oxide. It is soluble in acids. [1] [4] [5]
Uses
Owing to its solubility, antimony sulfate has uses in the doping of semiconductors. [6] It is also used for coating anodes in electrolysis and in the production of explosives and fireworks. [4]
Safety
Antimony(III) sulfate causes irritation to the skin and mucous membranes. [7]
Natural occurrence
Natural analogue of the exact compound is yet unknown. However, basic hydrated Sb sulfates are known as the minerals klebelsbergite [8] [9] and coquandite. [10] [9]
