Question

Name the anode ,cathode and electrolyte used in the lead storage battery.write the anode and cathode balanced reactions , including the overall discharge reaction that occurs In this battery?

Answer 1

The lead acid battery uses lead as the anode and lead dioxide as the cathode, with sulfuric acid as the electrolyte.

At the anode: Pb + HSO₄^- → PbSO₄ + H⁺ + 2e^-

At the cathode: PbO₂ + 3H⁺ + HSO₄^- + 2e^-→ PbSO₄ + 2H₂O

Overall: Pb + PbO₂ +2H₂SO₄ → 2PbSO₄ + 2H₂O
