A) \[{{H}_{2}}\] is cathode and \[Cu\] is anode
B) Oxidation occurs at \[Cu\] electrode
C) \[{{H}_{2}}\] is anode and \[Cu\] is cathode
D) reduction occurs at \[{{H}_{2}}\] electrode
Correct Answer: C
Solution :
We know that oxidation (loss of electrons) takes place at anode and reduction (gain of electron) takes place at cathode. Therefore, \[{{H}_{2}}\] is anode and \[Cu\] is cathode.
