Which of the following statements about the lead-acid battery is incorrect? Pb + PbO₂ + 4H⁺ + SO₄^{2 −} → 2PbSO₄ + 2H₂O A) Lead is oxidized. B) Lead oxide acts as the cathode. C) Both the anode and cathode reactions result in the formation of PbSO₄. D) Lead and lead oxide can be reformed from lead sulfate with the application of an outside electrical current. E) Porous lead plates act as the cathode.
