1.	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) How much electricity in terms of faraday is required to carry out the reduction of one mole of PbO_(2) ?
Answer» SOLUTION : ELECTRICITY in faradays to carry out the REDUCTION of one mole of `pbO_(2)=2` Faradyas
