Detailed Solution
Anode Pb(s)+SO42−(aq)⟶PbSO4(s)+2e− Cathode PbO2(s)+SO42−(aq)+4H++2e−⟶PbSO4(s) +2 H2O(l)Overall cell reaction Pb(s)+PbO2(s)+2H2SO4(aq)⟶2PbSO4(s)+2H2O(l)At the time of charging, a reverse reaction takes place. In which PbSO4 (s) at anode and cathode is converted into Pb and PbO2 respectively.
