Question
During discharge of a lead storage cell the density of sulphuric acid in the cell :
Options
A.Increasing
B.decreasing
C.remians unchanged
D.initially increases but decrease subsequently
Solution
Discharging reaction
Pb(s) + PbO2(s) + 2H2SO4 → 2PbSO4 + 2H2O.
Pb(s) + PbO2(s) + 2H2SO4 → 2PbSO4 + 2H2O.
