Question

Calculate the emf of the cell, $C d | C d^{2 +} (0.001 M) | | F e^{2 +} (0.6 M) | F e a t 25^{\circ} C$ .
The standard reduction potential of $C d / C d h 2 + and F e / F e^{2 +}$ electrodes are -0.403 and -0.441 volt respectively.

Solution

$E = E^{o} - \frac{0.0591}{n} l o g \frac{C d^{2 +}}{F e^{2 +}}$
$E = (0.403 - 0.441) - \frac{0.0591}{2} l o g \frac{0.001}{0.6}$
$E = 0.044 v$
