Question

For lead storage battery pick the the correct statements.

A. During charging of battery, PbSO₄ on anode is converted into PbO₂

B. During charging of battery, PbSO₄ on cathode is converted into PbO₂

C. Lead storage battery, consists of grid of lead packed with PbO₂ as anode

D. Lead storage battery has ~ 38% solution of sulphuric acid as an electrolyte

Choose the correct answer from the options given below:

(1) B, D only

(2) B, C, D only

(3) A, B, D only

(4) B, C only

Answer 1

Correct option is (1) B, D only

Lead storage battery consists of lead anode and a grid of lead packed with lead oxide (PbO₂) as cathode, a 38% solution of H₂SO₄ is used as an electrolyte.

On charging the battery the reaction is reversed and PbSO₄(s) on anode and cathode is converted into Pb and PbO₂ respectively.
