A lead storage battery is discharged. During the charging of this battery, the reaction that occurs at anode is

Options

A. `PbSO_(4) (s) + 2e^(-) to Pb(s) + SO_(4)^(2-)(aq)`
B. `PbSO_(4) (s)+ 2H_(2)O(l) to PbO_(2)(s) + SO_(4)^(2-)(aq) +4H^(+) + 2e^(-)`
C. `PbSO_(4) (s) to Pb(s) + SO_(4)^(2-)(aq)`
D. `PbSO_(4) (s)+ 2H_(2)O(l) + 2e^(-) to PbO_(2)(s) + SO_(4)^(2-)(aq) +2H^(+)`

Answer

A

Explanation

During charging, `PbSO_(4)` is converted to Pb at anode i.e.,
`PbSO_(4) (s) + 2e^(-) to Pb(S) + SO_(4)^(2-)(aq)`
