NEET Chemistry Electrolytic Cells MCQ Question
In an electrolytic cell, which ion is discharged at the cathode when a DC voltage is applied to copper strips in an aqueous solution of copper sulphate?
Cu2+ ions
Cu+ ions
Cu3+ ions
Cu(s) atoms
Correct Answer
Detailed Explanation
Cu2+ ions are discharged at the cathode during the electrolysis process, leading to the deposition of copper metal as per the reaction Cu2+ (aq) + 2e– → Cu (s).
