.Which of the following cell is not rechargeable?
Correct answer: A. Lead storage battery
- A. Lead storage battery
- B. Silver oxide cell
- C. Fuel cell
- D. Ni-Cd cell
Explanation
Lead-acid batteries, often used in cars, are not easily rechargeable. During discharge, they undergo chemical reactions that are not entirely reversible. Lead sulfate forms on the electrodes, hindering the efficient and complete reversal of the reactions, making them less suitable for multiple recharge cycles.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
