During discharge, the active material of both the positive and negative plates is changed to___________?
Correct answer: D. PbS04
- A. Pb
- B. Pb02
- C. PbO
- D. PbS04
Explanation
In a lead-acid cell, both plates progressively form lead sulphate during discharge: lead dioxide at the positive plate and spongy lead at the negative plate are converted to PbSO4. Therefore option D is correct.
