Question

 

1. Draw two labelled diagrams involving both electrolysis processes separately using 

graphite rods,

2. Give the half equations at the electrodes for both processes separately,

3. State the spectator ions for both processes and 

4. Give the complete equations for the two electrolysis processes.

Answer 1

Following reactions take place at anode and cathode

Anode : Cu→Cu+2

+2e−

Cathode : Cu+2+2e−→Cu
