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?)

✔ 最佳答案
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.

I'm really not quite sure, out of my knowledge in Organic Chem long time
ago, I can say I'm not sure: Potassium is metallic and gives positive ions
while the Cu is also on the positive anode. I don't think both positive ions will attract to form any deposit.
