While charging the lead storage battery

Options

A. `PbSO_(4)` on cathode is reduced to Pb
B. `PbSO_(4)` on anode is oxidized to `PbO_(2)`
C. `PbSO_(4)` on anode is reduced to Pb
D. `PbSO_(4)` on cathode is oxidized to Pb

Answer

C

Explanation

Reactions occuring during charging are :
`{:("Anode : "PbSO_(4(s))+2e^(-)rarr Pb_((s))+SO_(4(aq))^(2-)),("Cathode : "PbSO_(4(s))+2H_(2)OrarrPbO_(2(s))+SO_(4(aq))^(2-)+4H_((aq))^(+)+2e^(-)),(ulbar(2PbSO_(4(s))+2H_(2)OrarrPb_((s))+PbO_(2(s))+2H_(2)SO_(4(aq))" ")):}`
