?The exchange-current density for \(\mathrm{H}^{+}\) discharge at zinc is about \(50
Chapter 19, Problem E19D.8(a)(choose chapter or problem)
The exchange-current density for \(\mathrm{H}^{+}\) discharge at zinc is about \(50 \mathrm{\ pA} \mathrm{\ cm}^{-2}\) . Can zinc be deposited from an aqueous solution of a zinc salt under standard conditions and at \(25^{\circ} \mathrm{C}\)? The standard potential of the \(\mathrm{Zn}^{2+} \mid \mathrm{Zn}\) electrode is −0.76 V at \(25^{\circ} \mathrm{C}\).
