NEET Chemistry Electrolytic Cells MCQ Question
How much charge in coulombs is required for the reduction of 2 moles of Cu2+ to Cu in an electrolytic cell?
192,970 C
96,485 C
48,243 C
384,940 C
Correct Answer
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.
