Vanadium(III) sulfate is the inorganic compound with the formula V2(SO4)3. It is a pale yellow solid that is stable to air in contrast to most vanadium(III) compounds. It slowly dissolves in water to give the green aquo complex [V(H2O)6]3+.The compound is prepared by treating V2O5 in sulfuric acid with elemental sulfur:V2O5 + S + 3 H2SO4 → V2(SO4)3 + SO2 + 3 H2OThis transformation is a rare example of a reduction by elemental sulfur.
