For a metal electrode $M X^{2 +} / M$ at 298 K, the electrode potential is plotted against $lo g [M X^{2 +}]$ . The slope of the straight line obtained is (take $2.303 RT / F = 0.0591 V$ )

Nernst equation for

M X^{2 +} + 2 e X^{-} M

E = E^{\circ} + \frac{0.0591}{2} lo g [M X^{2 +}]

. The plot of

E

against

lo g [M X^{2 +}]

is a straight line with positive slope

0.0591/2 = 0.02955 \approx 0.0296 V

and intercept

E^{\circ}
