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