Nitrite can partially oxidize low-valent vanadium, but it depends on the chemical properties and reaction conditions of nitrite and vanadium. In some experiments, it is found that nitrite can oxidize V(II) ions into V(III) ions, but it cannot further oxidize V(III) into V(IV) or V(V).

There are other options for the oxidation of low-valent vanadium, such as oxidants (such as hydrogen peroxide and potassium permanganate). ) and heated in an oxygen atmosphere.
