During charging of a lead storage battery, the following reaction occurs at the cathode

Answer»

`Pb-2E^(-) to Pb^(2+)`
`Pb^(2+)+2e^(-) to Pb`
`Pb^(2-)+SO_(4)^(2-) to PbSO_(4)`
`PbSO_(4)+2H_(2)O to 2PbO_(2)+4H^(+)+SO_(4)^(2-)+2e^(-)`

Solution :During charging of lead ACCUMULATOR , REVERSE reaction takes place . `therefore` Pb plates become cathode.
