Consider the following set-up:

Cathode: Cu

Anode: Mg

Electrolyte: Potassium nitrate

Will potassium metal be formed on the surface of Cu electrode? (i.e. Will potassium ions accept electrons from Cu electrode?)

No. Instead, H+ ions(because solution, 有H2O, 佢會ioniae to form OH- and H+ ) will accept the electrons from Cu electrode (reduced) to form H2.

Since H+ ions has a higher oxidizing power than that of the K+ ions(睇番ECS)

(1) This is not Organic Chemistry.

(2) I wonder why you answered the question, when you were sure that you didn't know the answer.
