The answer is a non-negative integer. The standard oxidation potential of \( \mathrm{Ni} / \mathrm{Ni}^{2+} \) electrode is \( 0.236 \mathrm{~V} \). If this is combined with a hydrogen electrode in acid solution, at what \( \mathrm{pH} \) of the solution will the measured \( \mathrm{emf} \) be zero at \( 25^{\circ} \mathrm{C} \) ? (Assume \( \left[\mathrm{Ni}^{2+}\right]=1 \mathrm{M} \) and \( \left.p_{\mathrm{H}_{2}}=1 \mathrm{~atm}\right) \) 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
