Question

State True or False.
The dependence of electrode potential for the electrode $M^{n +} / M$ with concentration under STP condition is given by the expression:
$E = E^{o} + \frac{0.0591}{n} l o g_{10} [M^{n +}]$

Solution

The correct option is A True
According to Nernst equation:
$E = E^{o} - 0.0591 l o g Q / n$
So for
$M^{n +} + n e \to M$
$E = E^{o} - \frac{0.0591}{n} l o g_{10} M / [M^{n +}]$
$E = E^{o} + \frac{0.0591}{n} l o g_{10} [M^{n +}]$
