Question

Where does pure metal gets deposited after passing current?

(a) Cathode

(b) Anode

(c) Electrolyte

(d) Negative pole

I have been asked this question during an online interview.

I'm obligated to ask this question of Electroplating Equipment and Operating Conditions in section Electroplating of Engineering Chemistry II

Answer 1

Correct choice is (a) Cathode

The explanation is: During electroplating, impure metal is kept as anode and electrolyte is the metal salt solution. After the current has passed, the electrons will pass through the electrolyte and hence we will get the pure metal at anode.
