Explain the reactions taking place in the anode and cathode of a lead storage battery.

Answer»

Solution :Oxidation OCCURS at the anode
`""Pb_((s)) rarr PB^(2+)""_((aq))+2e^(-)`
The `pb^(2+)` ions combine with `SO_(4)^(-2)` to from `PbSO_(4)` precipitate.
`""Pb^(2+)""_((aq))+SO_(4)^(2-)""_((aq)) rarr PbSO_(4(s))`
REDUCTION occurs at the cathode
`PbO_(2(s))+4H_((aq))^(+)+2e^(-) rarr Pb_((aq))^(2+)+2H_(2)O(L)`
The `Pb^(2+)` ions also combine with `SO_(4)^(2-)` ions from sulphuric acid to form `PbSO_(4)` precipitate.
`""Pb_((aq))^(2+)+SO_(4(aq))^(-2) rarr PbSO_(4)`
