Which of the following oxides is used in lead storage battery
Options
(a) PbO
(b) PbO₂
(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.
