The standard oxidation potential of

\text{Ni} / \text{Ni}^{2+}

electrode is 0.236 V. If this is combined with a hydrogen electrode in acid solution, at what pH of the solution will the measured emf be zero at

25^\circ\text{C}

? (Assume

[\text{Ni}^{2+}] = 1 \text{ M}

and

P_{\text{H}_2} = 1 \text{ atm}
