Question

0.27 A sample of Fe (S04), and FeC204 was dissolved in dil.
H,SOThe complete oxidation of reaction mixture required
40ml of N/16 KMnO, After the oxidation, the reaction
mixture was reduced by Zn and dil. H.S04. On again
oxidation by same KMnO4, 60ml were required. The ratio
of millimoles of Fe (SO4)3 and FeC204 is 7: A. Find the
value of A. (mol wt. Fe2(SO4)3 = 400).
