NEET Chemistry Electrolytic Cells MCQ Question
Which of the following statements about electrolytic cells is correct?
An electrolytic cell requires an external voltage to drive a non-spontaneous reaction.
Copper is deposited at the anode during the operation of an electrolytic cell.
Electrolytic cells can only operate with aqueous solutions.
An electrolytic cell generates electrical energy from spontaneous chemical reactions.
Correct Answer
Detailed Explanation
An electrolytic cell uses an external source of voltage to drive a chemical reaction, which is non-spontaneous. Copper is actually oxidized at the anode, not deposited there, and electrolytic cells can operate with non-aqueous solutions as well. They do not generate energy but require energy input.
