Question

During discharging the change taking place at cathode in lead accumulator is:

विकल्प

• Pb_(s) is oxidized to \[\ce{Pb^{2+}_{(aq.)}}\]

• \[\ce{Pb^{2+}_{(aq.)}}\] is oxidized to PbO_2(s)

• \[\ce{Pb^{2+}_{(aq.)}}\] is reduced to Pb_(s)

• PbO_2(s) is reduced to \[\ce{Pb^{2+}_{(aq.)}}\]

Answer 1

PbO_2(s) is reduced to \[\ce{Pb^{2+}_{(aq.)}}\]
