Answer 1

Explanation:

In the beginning OH- ions get discharged at anode and H+ ions remain in the solution. Therefore, pH of the solution decreases. Once all Cu+2 ions are consumed, H+ ions start getting discharged at cathode. Therefore, pH of the solution increases.

Answer 2

Answer:

In the beginning OH- ions get discharged at anode and H+ ions remain in the solution. Therefore, pH of the solution decreases. Once all Cu+2 ions are consumed, H+ ions start getting discharged at cathode. Therefore, pH of the solution increases.
