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