Consider the electrode/water-based solution interface Pt/Ag+ (0.01M), Cd^2+ (0.01M), HClO4 (1M) .
Write the equation (s) for the electrode reaction(s) that occur at applied potentials of:
1.4 V, 0.6 V, 0.2 V, and -0.5 V (NHE)
At anode, oxidation takes place i.e loss of electrons,
Ag ---------------→ Ag+ + e-
Whereas at cathode, reduction ...
