If stoichiometric quantities of `KMnO_(4) and K_(2)Cr_(2)O_(7)` mixture is added for the oxidation of `Fe^(2+) " to " Fe^(3+)` in acidic medium, then `Fe^(2+)` will be oxidised

Options

A. equally by `KMnO_(4) and K_(2)Cr_(2)O_(7)`
B. more by `KMnO_(4)`
C. more by `K_(2)Cr_(2)O_(7)`
D. no reaction

Answer

B

Explanation

`KMnO_(4) + K_(2)Cr_(2)O_(7)`
In this process `KMnO_(4)` is strong oxidising agent in acidic medium. It oxidises `Fe^(2+) " to . Fe^(3+). K_(2)Cr_(2)O_(7)` is weak oxidising agent in acidic medium.
