Question

Active materials of a lead acid cell are

• A. spongy lead
• B. lead peroxide
• C. dilute H2SO4
• D. all of these

Hint:

In a lead-acid battery, spongy lead, lead peroxide, and dilute sulfuric acid are the key active materials.

Answer 1

The Correct Option is D

Step 1: Components of a lead acid cell.
The active materials in a lead-acid cell include spongy lead (Pb) on the negative plate, lead peroxide (PbO₂) on the positive plate, and sulfuric acid (H₂SO₄) as the electrolyte.
Step 2: Conclusion.
Thus, all the given materials are part of a lead-acid cell, corresponding to option (D).
