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

Explanation

Lead storage battery is a secondary cell that can be charged by passing a current. Reactions occurring in the lead storage battery while operating (during discharge) are:
`{:("At cathode", PbO_(2) + SO_(4)^(2-) + 4H^(+) + 2e^(-) to PbSO_(4) + 2H_(2)O),("At anode", Pb + SO_(4)^(2-) to PbSO_(4) + 2e^(-)),("overall reaction", Pb + PbO_(2) + 2H_(2)SO_(4) to 2PbSO_(4) + 2H_(2)O):}`
