A sample of FeSO4 and FeC2O4 was dissolved in dilute sulphuric acid. The complete oxidation of the reaction mixture required 40 mL of N/15 KMnO4. after the oxidation, the reaction mixture was reduced by Zn and H2SO4. On using the same solution of KMnO4 to oxidize the resulting solution, 25 mL was required. Calculate the ratio of equivalents of Fe in oxalate and Fe(II) sulphate. (Fe: 56)

Answer» A sample of $F e S O_{4}$ and $F e C_{2} O_{4}$ was dissolved in dilute sulphuric acid. The complete oxidation of the reaction mixture required 40 mL of N/15 $K M n O_{4} .$ after the oxidation, the reaction mixture was reduced by Zn and $H_{2} S O_{4} .$ On using the same solution of $K M n O_{4}$ to oxidize the resulting solution, 25 mL was required. Calculate the ratio of equivalents of Fe in oxalate and Fe(II) sulphate. (Fe: 56)
