Electrochemical and Electrolytic Cell:
The following are the points of difference between Electrochemical and Electrolytic Cell-
| Electrochemical Cell | Electrolytic Cell |
|---|---|
| Electrical energy is produced in this cell. | Electrical energy is consumed in this cell. |
| The reaction taking place in this cell is spontaneous. | The reaction taking place in this cell is non-spontaneous and it takes place only when electrical energy from outside is supplied. |
| The two electrodes are set up in two different containers containing different electrolytes and the two half cells thus formed are connected through a salt bridge. | Both the electrodes are placed in the solution or molten electrolyte in the same container. |
| An anode is a negative electrode and a cathode is positive. | An anode is a positive electrode and a cathode is negative. |
| Electrodes used in two half-cells are of different materials. | Electrodes may be of the same or different materials. |
| The electrons move from anode to cathode in an external circuit. | The electrons are supplied by the external source. They enter through a cathode and come out through an anode. |
