Write the cell reaction which occur in the lead storage battery 1. When the battery is in use, 2. When the battery is charging.

Answer»

1. Pb(s) + PbO₂(s) + 2H₂SO₄ (aq) → 2PbSO₄ (s) + 2H₂O(l)

At anode: Pb(s) + SO₄^2- → PbSO₄ (s) + 2e^-

At cathod: PbO₄ (s) + SO^2- (aq) + 4H⁺ (aq) + 2e^- → PbSO₄ (s) + 2H₂O(l)

2. 2PbSO₄ (s) + 2H₂O(s) → PbSO₄ (s) + 2H₂SO₄ (aq)
