On discharge of a lead acid battery :
Anodic reaction: Pb(s) + SO₄²⁻(aq) → PbSO4(s) + 2e⁻
Cathodic reaction: PbO₂(s) + 4H⁺(aq) + SO₄²⁻(aq) + 2e⁻ → PbSO₄(s) + 2H₂O(l)
Hence, the overall reaction is:
Pb(s) + PbO₂(s) + 4H⁺(aq) + 2 SO₄²⁻(aq) → 2PbSO₄(s) + 2H₂O(l
Anodic reaction: Pb(s) + SO₄²⁻(aq) → PbSO4(s) + 2e⁻
Cathodic reaction: PbO₂(s) + 4H⁺(aq) + SO₄²⁻(aq) + 2e⁻ → PbSO₄(s) + 2H₂O(l)
Hence, the overall reaction is:
Pb(s) + PbO₂(s) + 4H⁺(aq) + 2 SO₄²⁻(aq) → 2PbSO₄(s) + 2H₂O(l
