Question

ix. The oxidation reaction that takes
place in lead storage battery during
discharge is
a. Pb2® (aq) +S0,20(aq) - PbSO4(s)
b. PbSO (s)+2H,0() - PbO (5)
+ 4H®(aq) + SO_20(aq) + 2e0
c. Pb(s)+SO_20(aq) > PbSO,(s)+
4
2e
d. PbSO (s) + 2e - → Pb(s)
+ SO 2º(aq)​

Answer 1

The recharging of a discharged lead storage cell/battery. In the discharged state, that lead (Pb) of the anond, and the lead dioxide (PbO2) of the cathode are completely converted to lead sulphate (PbSO4). the water produce in the reaction dilutes the sulfuric acid.

I HOPE IT HEIP YOU.
