Interpretation: Difference between a galvanic cell and an electrolytic cell needs to be explained.
Concept Introduction:
Answer to Problem 1RQ
Difference between a galvanic cell and an electrolytic cell is as follows:
Galvanic cell | Electrolytic cell |
It transfers chemical energy into electrical energy. | It transfers electrical energy into chemical energy. |
Anode is a negative electrode | Anode is a positive electrode |
Cathode is a positive electrode | Cathode is a negative electrode |
Explanation of Solution
In a galvanic cell, chemical energy is changed to electrical energy while in electrolytic cell electrical energy changes to chemical energy.
In a galvanic cell, oxidation results at the anode and reduction takes place at the cathode. In an electrolytic cell, oxidation occurs at cathode and reduction occurs at the anode.
