Write cell reaction in lead storage battery during discharge.
Advertisements
उत्तर
The electrode reaction that occurs during discharge.
At anode
`Pb_((s))+SO_(4(aq))^-2->PbSO_(4(s))+2e^-`
At Cathode
`PbO_(2(s)) + 4H_((aq))^+ +SO_(4(aq))^(2-) +2e^- ->PbSO_(4(s))+2H_2O (l)`
Overall reaction
`Pb_((s))+PbO_(2(s))+4H_((aq))^+ +2SO_(4(aq))^-2->2PbSO_(4(s))+2H_2O`
