NEET Chemistry Electrolytic Cells MCQ Question
What is the reaction that occurs at the cathode in an electrolytic cell consisting of copper strips in copper sulfate solution?
Cu²⁺(aq) + 2e⁻ → Cu(s)
Cu(s) → Cu²⁺(aq) + 2e⁻
Cu²⁺(aq) → Cu(s) + 2e⁻
Cu(s) + 2e⁻ → Cu²⁺(aq)
Correct Answer
Detailed Explanation
At the cathode in an electrolytic cell, Cu²⁺ ions are discharged and reduced to solid copper, as represented by the reaction Cu²⁺(aq) + 2e⁻ → Cu(s). This process is fundamental to the deposition of copper metal on the cathode during electrolysis.
