What type of a battery is lead storage cell ? Write the anode and cathode reaction and overall reaction occurring in a lead storage battery during discharging and recharging of cell.

Text Solution

Verified by Experts

It is a secondary cell.
`{:("Anode reaction :",P+SO_(4)^(2-)rarrPbSO_(4)+2e^(-)),("Cathode reaction :",PbO_(2)+4H^(+)+SO_(4)^(2-)+2e^(-)rarr PbSO_(4)+2H_(2)O):}`
`Pb(s)+PbO_(2)+2H_(2)SO_(4)overset("Discharging")underset("Recharging")hArr 2PbSO_(4(s))+2H_(2)O(l)`
