Question
While charging lead storage battery
Options
PbSO4 on cathode is reduced to Pb
PbSO4 on anode is oxidised to PbO2
PbSO4 on anode is reduced to Pb
PbSO4 on cathode is oxidised to Pb
Solution
PbSO4 on anode is reduced to Pb
Explanation:
Charging: anode: \[\ce{PbSO4_{(s)} + 2e^- -> Pb_{(s)} + SO^{-2}_{4(aq)}}\]
Cathode: \[\ce{PbSO4_{(s)} + 2H2O_{(l)} -> PbO2_{(s)} + SO^{-2}_{4(aq)} + 2e^-}\]
