Step 1:
\Differences between electrolytic cell and Chemical/Volatile cell:
\\
| \ | Electrolytic Cell (Electrolysis) | \Chemical Cell / Voltaic Cell | \
| Structure | \With electrical supply. | \No electrical supply. | \
| Electrodes | \Can be the same or difference metal (graphite or platinum). | \Must be two different metals. | \
| Flows of electrons | \From anode to cathode through external circuit. | \From more electropositive metal to less electropositive metal through external circuit. | \
| Transformation of energy | \Electrical energy to chemical energy. | \Chemical energy to electrical energy. | \
| At positive terminal | \Anode.Oxidation occurs. Anions release electrons at the anode. | \Cathode.Reduction occurs. \
Oxidising agent gain electrons. \ | \
| At negative terminal | \Cathode.Reduction occurs. \
Cations gain electrons from the cathode. \ | \
Anode.Oxidation occurs. \
Reducing agent releases electrons. \ | \
- Both Electrolytic and voltaic cell use redox reaction.
\-The anode is the site of oxidation in both Electrolytic and voltaic cell.
\-The cathode is the site of reduction in both Electrolytic and voltaic cell.
\-The electrons flow through the wire from anode to cathode in both Electrolytic and voltaic cell.
