MCQ
Assertion : During electrolysis of $CuSO_4(aq)$ using copper electrodes, copper is dissolved at anode and deposited at cathode.

Reason : Oxidation takes place at anode and reduction at cathode.

  • ✓
    If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
  • B
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
  • C

Answer

Correct option: A.
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
a
At cathode : $C{u^{2 + }}(aq)\, + \,2{e^ - }\, \to \,\mathop {Cu(s)}\limits_{{\text{(Reduction)}}} \,$

At anode : $Cu(s)\, \to \,\,C{u^{2 + }}(aq)\,\mathop { + \,2{e^ - }\,}\limits_{{\text{(Oxidation)}}} $
