NEET Chemistry Electrolytic Cells MCQ Question
What occurs at the cathode in an electrolytic cell involving copper sulfate?
Copper ions are reduced to copper metal.
Copper metal is oxidized to copper ions.
Copper ions are formed from copper metal.
No reaction takes place at the cathode.
Correct Answer
Detailed Explanation
At the cathode, Cu2+ ions gain electrons and are reduced to solid copper, as indicated by the reaction Cu2+ (aq) + 2e– → Cu (s). This is a key process in the operation of electrolytic cells.
