In a lead storage battery, what lead compound is formed at both the cathode and the anode during discharge?

Question

Quizplus · Accepted Answer

During discharge, lead sulfate (PbSO4) is formed at both the cathode and anode in a lead storage battery. The chemical reaction can be represented as follows:
PbO2 (cathode) + Pb (anode) + 2H2SO4 (electrolyte) → 2PbSO4 (both cathode and anode) + 2H2O
Therefore, option C, lead sulfate (PbSO4), is the correct answer. Options A and D may be formed during charging, while option B is not a common lead compound formed in lead-acid batteries.
