What type of a battery is lead storage battery? Write the anode and the cathode reactions and the overall reactions occurring in a lead storage battery.

Text Solution

Verified by Experts

The lead storage battery is most important secondary cell. The celi reactions when the battery is in use -
At anode : `Pb(s) +SO_4^(2-)(aq) toPbSO_4(s) +2e^-`
At Cathode :`PbO_2(s) +SO_4^(2-)(aq)+2e^(-)toPbSO_4(s) +2H_2O(l)`
The overall cell reaction is
`Pb(s) +PbO_2(s) +2H_2SO_4(aq)to2PbSO_4(s) +2H_2O(l)`
