What are the difference between Electrochemical and Electrolytic cell?
- It converts chemical energy (of a redox reaction) into electrical energy.
- At the electrodes, spontaneous redox reaction takes place.
- The electrodes are made of dissimilar metals.
- Each electrode is dipped in electrolytic solution of its own ions.
- Salt bridge is used.
- Anode is negative electrode and cathode is positive electrode of the cell.
- It converts electrical energy (from an external source) into chemical energy.
- At the electrodes, non‐spontaneous redox reaction takes place only when electrical energy is supplied.
- The electrodes may be made of same or different metals.
- Both the electrodes are inserted in the same electrolyte solution.
- Salt bride is not used.
- Anode is positive electrode and cathode is negative electrode of the cell.
