During the titration of oxalic acid againts KMnO_(4) , the auto catalyst used is

Ammonium vanadate on theating with oxalic acid forms a compound (Z) . A sample of (Z) was titrated with 1 M KMnO_(4) solution in hot acidic medium. The resulting solution was reduced with SO_(2) , the excess of SO_(2) is boiled out and the solution was again titrated with 1 M KMnO_(4) . The volume ratio of KMnO_(4) used in two titrations was 5:1 . Given that KMnO_(4) oxidised all oxidation states of vanadium to +5 and SO_(2) reduced to +4 . Find the oxidation state of V in Z .
