During charging of lead storage bttery, the reaction occurring at the cathode is:-

Answer»

`Pb^(2+)+2etoPb`
`PbtoPb^(2+)+2e`
`PbSO_(4)+2H_(2)OtoPbO_(2)+4H^(+)+SO_(4)^(2-)+2e^(-)`
`Pb^(2+)+SO_(4)^(2-)toPbSO_(4)`

Solution :In an UNCHARGED condition, in LEAD storage BATTERY, the reaction occurring at the cathode is,
`PbO_(2)+4H^(+)+SO_(4)^(2-)+2e^(-)toPbSO_(4)+2H_(2)O`
During charging of lead storage battery, the reaction is REVERSED at both anode and cathode. The reaction occurring at the cathode is,
`PbSO_(4)+2H_(2)OtoPbO_(2)+4H^(+)+SO_(4)^(2-)+2e^(-)`
