NEET Chemistry Electrolytic Cells Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Cathode Reaction | (i) Cu 2+ (aq) + 2e – → Cu (s) |
| (b) Anode Reaction | (ii) Cu(s) → Cu 2+ (aq) + 2e – |
| (c) Charge Required for Cu 2+ | (iii) 2 moles of electrons |
| (d) Charge Required for Ag + | (iv) 1 mole of electron |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-i, b-ii, c-iv, d-iii
a-ii, b-iv, c-iii, d-i
Correct Answer
Detailed Explanation
In an electrolytic cell, the cathode reaction involves the reduction of Cu 2+ ions to copper metal, while the anode reaction involves the oxidation of solid copper to Cu 2+ ions. The charge required for the reduction of Cu 2+ is 2 moles of electrons, and for Ag +, it is 1 mole of electron as each silver ion requires one electron for reduction.
