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) Cathode reaction (i) Cu 2+ (aq) + 2e – → Cu (s) (b) Anode reaction (ii) Cu(s) → Cu 2+ (aq) + 2e – (c) Electrolytic cell (iii) External voltage applied (d) Electrolysis product (iv) Copper ions discharged
Choose the correct matching:
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iv, b-iii, c-i, d-ii
D
a-iii, b-iv, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
In an electrolytic cell, the cathode reaction involves the discharge of copper ions as per the reaction Cu 2+ (aq) + 2e – → Cu (s), while at the anode, copper is oxidized to copper ions. An external voltage is indeed required to drive the process.
