A lead storage battery is the most important 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)`) The battery holds 35L of the acid. During the discharge of the battery, the density of `H_(2)SO_(4)` falls to 1.138 g `mL^(-1)`. (20%`H_(2)SO)_(4)` by mass)
What is the molarity of sulphuric acid before discharge ?

Text Solution

Verified by Experts

Molarity `=(38xx1.294)/(98)xx(1000)/(100)=5.02M`

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) Lead storage battery is considered a secondary cell. Why?
