While charging the lead storage battery:

Options

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

Answer

C

Explanation

The cell reaction s during chargin of lead stroage battery are
At anode `PbSO_(4) (s) +2e^(-) rarr Pb(s) + SO_(4)^(2-) (Aq)`
At cathode `PbSO_(4) (S)+2H_(2)O(l) rarr PbO_(2)(s) +SO_(2)O(l) rarr PbO_(2)(s)+sO_(4)^(2-) (aq)+4H^(+)(aq)+2e^(-)`
so `PbSO_(4)` at anode is reduced to Pb
