Which of the following statements about the electrolysis of CuSO4(aq) using copper cathode and platinum anode is not correct?
- Copper is deposited at the cathode
- Oxygen is liberated at the anode
-
it is used for the purification of copper
- The solution becomes acidic
The correct answer is: C
Explanation
For purifying impure copper, the anode electrode is impure copper while the cathode electrode is pure copper, but for this question, two different electrodes were used, hence option C is the correct option to this question.
