Grace Hill · Answer 1

The cathode is the electrode where the reduction takes place.

Explanation:

Cell has three components:

an electrolyte and two electrodes which is a cathode and an anode.

Electrolyte is usually solution of the water or other solvents in which the ions are dissolved.

In electrolytic cell:

Negatively charged electrode is the cathode where the process of reduction takes place.

Positively charged electrode is the anode where the process of oxidation takes place.

In galvanic cell:

Positively charged electrode is the cathode where the process of reduction takes place.

Negatively charged electrode is the anode where the process of oxidation takes place.

So, the correct answer is - The cathode is the electrode where the reduction takes place.
