3 B, C, D only  
4 B, C only  

Ans.

(2)

Lead storage battery consists of lead anode and a grid of lead packed with lead oxide (PbO2) as cathode. A 38% solution of H2SO4 is used as an electrolyte. On charging the battery the reaction is reversed and PbSO4(s) on anode and cathode is converted into Pb and PbO2 respectively.
