Gallium(III) sulfate

Gallium(III) sulfate refers to the chemical compound, a salt, with the formula Ga2(SO4)3, or its hydrates Ga2(SO4)3·xH2O.

Gallium metal dissolves in sulfuric acid to form solutions containing [Ga(OH2)6]3+ and SO42− ions.

[1] Anhydrous Ga2(SO4)3 is isostructural with iron(III) sulfate, crystallizing in the rhombohedral space group R3.

[4] Gallium(III) sulfate is prepared from the reaction of hydroxygallium diacetate and sulfuric acid.

Jarosite and alunite can contain a small amount of gallium substituted for iron or aluminium.
