The equation for one of the half-reactions in a lead storage battery is : PbO-(2) + 4H^(+) + SO_(4)^(2-) + 2e^(-) rightarrow PbSO_(4) + 2H_(2)O What happens to the properties of the electrolyte as this

The overall reaction for the lead storage batter when it discharges is: Pb(s) + PbO_(2)(s) + 4H^(+)(aq) + 2SO_94)^(2-)(aq) rightarrow 2PbSO_(4)(s) + 2H_(2)O(l) (P) PbSO_(4) is formed only at the cathode. (Q) The density of the solution decreases. Which statements correctly describes the battery as its discharges?

A read storage battery is the most impotant type of secondary cell having a lead anode and a grid of lead packed with PbO_(2) as cathode. A 38% solution of sulphuric acid is used as electrolyte. (Density=1.294 g mL^(-1)) battery holds 3.5 L of the acid. During the discharge of the battery, the density of H_(2)SO_(4) falls to 1.139 g mL^(-1).(20%H_(2)SO_(4) by mass) Write the reaction taking place at the cathode when the battery is in use.
