A sample of Fe2(SO4)3 and FeC2O4 was dissolved in dil H_2SO_4. The complete oxidation of reaction mixture req. 40 ml of N/16 KMnO_4. After the oxidation mixture was reduced by Zn and dil. H_2SO_4. On again oxidation by same KMnO_4, 60 ml were require. Calculate the ratio of millimoles of Fe_2(SO_4)_3 and FeC_2O_4 in mixture. |
