Vanadium compounds in reductimetric titrations-III: Applications of vanadium(II).
Vanadium(II) sulphate is a versatile reductant; it can change its oxidation number by one, two, or three units, depending on the oxidation potential of the half-cell with which it reacts and on the mode of titration. The end-point of many of the reactions can be detected by means of indicators. A back-titration method is usually needed for the three-electron oxidation of vanadium(II).
