NEET Chemistry Electrolytic Cells Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Electrolytic cell | (i) Cu(s) to Cu2+(aq) |
| (b) Reduction at cathode | (ii) Cu2+(aq) to Cu(s) |
| (c) Oxidation at anode | (iii) External voltage source |
| (d) Copper deposition | (iv) Chemical reaction with energy input |
a-iii, b-ii, c-i, d-iv
a-ii, b-i, c-iii, d-iv
a-iv, b-ii, c-iii, d-i
a-iii, b-i, c-ii, d-iv
Correct Answer
Detailed Explanation
In an electrolytic cell, an external voltage source drives the non-spontaneous chemical reaction. The cathode undergoes reduction (Cu2+ to Cu), while oxidation occurs at the anode (Cu to Cu2+). Copper deposition at the cathode is a result of this process.
