Question

Which statements about the lead-acid battery is correct? Pb + PbO₂ + 4H⁺ + SO₄^{2 −} → 2PbSO₄ + 2H₂O

Quizplus · Accepted Answer

All of the statements are correct. The lead-acid battery is a rechargeable battery that uses lead and lead oxide as the electrodes and sulfuric acid as the electrolyte. During discharge, lead is oxidized and lead oxide is reduced, resulting in the formation of lead sulfate on both electrodes. When the battery is recharged, an outside electrical current is applied, which reverses the reactions and reforms lead and lead oxide from the lead sulfate.
