Vanadyl(IV) sulfate is a blue crystalline solid that is normally stable in room conditions. It is a moderately strong reducing agent, being oxidized in acidic solution to the vanadyl(V) ion and in alkaline solutions to the vanadate ion, both of which are yellow-orange in colour. It is reduced by zinc amalgam to a mixture of green vanadium(III) and purple vanadium(II) ions.
