NEET Chemistry Electrolytic Cells MCQ Question
Type: MCQ-numerical-Medium-Class 12
How much charge in coulombs is required for the reduction of 2 moles of Cu2+ to Cu in an electrolytic cell?
A
192,970 C
B
96,485 C
C
48,243 C
D
384,940 C
Correct Answer
Option A
Detailed Explanation
The reduction of Cu2+ to Cu requires 2 moles of electrons per mole of Cu2+. Thus, for 2 moles of Cu2+, 4 moles of electrons are needed. Since 1 mole of electrons corresponds to 96,485 C, the total charge needed is 4 × 96,485 C = 192,970 C.
