Problem

The magnitude of the change in oxidising power of the

\text{MnO}_4^-/\text{Mn}^{2+}

couple is

x \times 10^{-4}\text{ V}

, if the

\text{H}^+

concentration is decreased from 1 M to

10^{-4}\text{ M}

25^\circ\text{C}

. (Assume concentration of

\text{MnO}_4^-

and

\text{Mn}^{2+}

to be same on change in

\text{H}^+

concentration). The value of

x

is ____. (Rounded off to the nearest integer) Given:

\frac{2.303RT}{F} = 0.059
