Question

Differentiate between a electrochemical cell and a electrolytic cell. [5 MARKS]

Answer 1

In Electrochemical cell
1) Electrical energy is produced.
2) Reaction taking place is spontaneous.
3) The two half cells are set up in different containers and are connected through salt.
4) Anode is negative and cathode is positive.
5) The electrons move from anode to cathode in external circuit.

In Electrolytic Cell
1) Electrical energy is consumed.
2) Reaction taking place is nonspontaneous.
3) Both the electrode are placed in the solution.
4) Anode is positive and cathode is negative.
5) Electrons enter through cathode and come out through anode.
