Question

How can you increase the reduction potential of an electrode?

Answer 1

Reduction potential of an electrode is given by

\[\ce{E_{M^{n+}/M} = E^{\circ}_{M^{n+}/M} - \frac{2.303 RT}{nF} log_10 \frac{1}{[M^{n+}_{ (aq)}]}}\]

It is clear that increasing the concentration of Mⁿ⁺ ions at room temperature may increase \[\ce{E_{M^{n+}/M}}\]. It can also be increased by increasing the electrode assembly's temperature.
