NEET Chemistry Electrolytic Cells Assertion Reason Question
Assertion (A): In an electrolytic cell, copper is deposited at the cathode. | Reason (R): In an electrolytic cell, copper ions are reduced to copper metal at the cathode as Cu 2+ (aq) + 2e – → Cu (s).
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The NCERT context explains that in an electrolytic cell, copper ions are reduced at the cathode, resulting in the deposition of copper metal. This supports both the assertion and the reason.
