Solution

The correct option is C Migration of ions along with oxidation reaction at anode and reduction at cathode
In an electrolytic cell, the electron flows from anode to cathode through external circuit. Oxidation occurs at anode and reduction occurs at cathode.
The cell has an electrolyte, two electrodes and direct current supply. An electrolyte is an ionic compound, which ionises on passing current. In this process, the negative ions are discharged at positive electrode (anode) and positive ions are discharged at negative electrode (cathode).

Q. Assertion: Starting from aq. copper [II] sulphate solution, equations for the reactions at the cathode and anode during electrolysis of aq.

C u S O_{4}

using active copper electrodes is;
at anode:
