Indium(III) sulfate hydrate (In2(SO4)3•xH2O (x≈6))-Powder

Characteristic

Indium(III) sulfate (In₂(SO₄)₃) is a sulfate salt of the metal indium. It is a sesquisulfate, meaning that the sulfate group occurs 3/2 times as much as the metal. It may be formed by the reaction of indium, its oxide, or its carbonate with sulfuric acid. An excess of strong acid is required, otherwise insoluble basic salts are formed.As a solid indium sulfate can be anhydrous, or take the form of a pentahydrate with five water molecules or a nonahydrate with nine molecules of water.
