Question

Give two differences between Galvanic Cell and Electrolytic cell.

Hint:

In both cells, oxidation always occurs at the anode and reduction at the cathode. Only the sign changes.

Answer 1

1. Energy Conversion: A Galvanic cell converts chemical energy into electrical energy (spontaneous reaction). An Electrolytic cell converts electrical energy into chemical energy (non-spontaneous reaction).
2. Polarity of Electrodes: In a Galvanic cell, the anode is negative and the cathode is positive. In an Electrolytic cell, the anode is positive and the cathode is negative.
