Calculate the potential for each cell and indicate whether the metal electrode in the half-reaction opposite the standard hydrogen electrode (SHE) would be the anode or the cathode if the cell was shorted and electrons were allowed to flow freely at 25 °C.
SHE || Zn^2+(aq, 0.0110 M) | Zn(s)
E°Zn^2+/Zn = -0.762 V
The Zn electrode is the cathode.
anode.
Ecell = V
Pt(s) | V^3+(aq, 0.460 M), V^2+(aq, 0.01000 M) || SHE
E°V^3+/V^2+ = -0.255 V
The Pt electrode is the anode.
cathode.
Ecell = V
