Question

A certain amount of a reducing agent reduces x mole of KMnO4 and y mole of K2Cr2O7 in different experiments in acidic medium. If the change in oxidation state in reducing agent is same in both experiments, x: y is

Options

A.5: 3
B.3: 5
C.5: 6
D.6: 5

Solution

$x \times 5 = y \times 6 \Rightarrow x:y = 6:5$
