(c) Pb₂O₃
(d) Pb₃O₄

Correct Answer:

PbO₂

Explanation:

Lead storage battery consists of a group of lead plates bearing compressed spongy lead, alternating with a group of lead plated bearing lead dioxide, PbO₂. These plates are immersed in a solution of about 30% H₂SO₄. Overall cell reaction is
Pb + PbO₂ + 4H⁺ +2SO₄²⁻ → 2PbSO₄ + 2H₂O
E (Cell) is 2.041 Volt.
