Writing an equation for electrode reactions when considering electrode/water-based solution interface

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)

Solution Preview

At anode, oxidation takes place i.e loss of electrons,
Therefore,

Ag ---------------→ Ag+ + e-

Whereas at cathode, reduction ...

Solution Summary

Expert provides brief equational information on how to write an equation for an electrode reaction, which occur at the provided applied potentials. Solution considers an electrode/water-based solution interface.
