For lead storage battery pick the correct statements A. During charging of battery, PbSO 4 on anode is converted into PbO 2 B. During charging of battery, PbSO 4 on cathode is converted into PbO 2 C. Lead storage battery consists of grid of lead packed with PbO 2 as anode D. Lead storage battery has ~ 38 % solution of sulphuric acid as an electrolyte Choose the correct answer from the options given below:

Options

  1. AA, B, D only
  2. BB, C, D only
  3. CB, C only
  4. DB, D only

Correct answer

D. B, D only

Step-by-step solution

The lead storage battery is as shown in diagram. Lead storage battery consists of lead anode and a grid of lead packed with lead oxide( PbO 2 ) as cathode, a 38 % solution of H 2 SO 4 is used as an electrolyte. During charging of battery PbSO 4 deposited on cathode is converted in PbO 2 and PbSO 4 deposited on anode is converted into Pb . The electrolyte used in battery is H 2 SO 4 which is about 38 % by mass.
