Question
When a lead storage battery is discharged :
Options
A.SO2 is evolved
B.lead is formed
C.lead sulphate is consumed
D.sulphuric acid is consumed
Solution
FactualDuring discharge following reaction takes place.
Pb(s) + 2H2SO4- + 2H3O+ + PbO2(s) → 2PbSO4(s) + 4H2O Eo = 2.041V
Pb(s) + 2H2SO4- + 2H3O+ + PbO2(s) → 2PbSO4(s) + 4H2O Eo = 2.041V
