Chemistry-Electrolytic Cells
NEET Chemistry Electrolytic Cells Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
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
Choose the correct matching:
A
a-iii, b-ii, c-i, d-iv
B
a-ii, b-i, c-iii, d-iv
C
a-iv, b-ii, c-iii, d-i
D
a-iii, b-i, c-ii, d-iv
Correct Answer
Option A
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.
