Indium(I) sulfate, In2SO4 can be made in a solid state by heating indium metal with indium(III) sulfate, but when dissolving in water or sulfuric acid, In+ reacts to produce hydrogen gas.
Indium(I) sulfate, In2SO4, is synthesized as a solid by heating indium metal and indium(III) sulfate. When dissolved in water or sulfuric acid, the compound reacts to produce hydrogen gas. A single molecule of Indium(I) sulfate can break down into thousands of hydrogen molecules.
