Question

If equal volumes of 0.1 M $KMnO_4$ and 0.1 M $K_2Cr_2O_7$ solutions are allowed to oxidize $Fe^{2+}$ to $Fe^{3+}$ in an acidic medium, then the amount of $Fe^{2+}$ oxidized will be:

Prashant Kotian · Accepted Answer

Correct answer: B. The oxidizing capacity depends on the normality. For in acid, n=5, so Normality = 0.5 N. For in acid, n=6, so Normality = 0.6 N. Since 0.6 N > 0.5 N, the dichromate solution contains more equivalents per unit volume and will oxidize more .
