Which of the following reactions occurs at the anode during the recharging of lead storage battery ?

Options

A. `Pb^(2+)+2e^(0)rarrPb`
B. `Pb^(2+)+SO_(4)^(2-)rarrPbSO_(4)`
C. `PbrarrPb^(2+)+2e^(-)`
D. `PbSO_(4)+2H_(2)Orarr2PbO_(2)+4H^(+)+SO_(4)^(2-)+2e^(-)`

Answer

D

Explanation

During discharging both the plates are converted into `PbSO_(4)` During charging `PbSO_(4)` is converted into `PbO_(2)` and `Pb` at +ve and -ve electrodes respectively.
