A sample of ferrous sulphate and ferrous oxalate was dissolved in dil. H_(2)SO_(4) the complete oxidation of reactionmixture required 40 mL pf N//15 KMnO_(4). After the oxidation, the reactionmixture was reduced by Zn and H_(2)SO_(4). On again oxidation by same KMnO_(4), 25mL were required. Calucate the ratio of fe in ferrous sulphate and oxalate.
