Question

Which of the following is not a feature of the lead storage battery?a.The electrolyte is hydrochloric acid.b.Lead is oxidized at the anode.c.PbO2 is reduced at the cathode.d.Lead (II) sulfate forms during discharge and sticks to the electrodes.e. The lead storage battery is a secondary cell.

Answer 1

The feature of the lead storage battery that is not correct is:

a. The electrolyte is hydrochloric acid.

The electrolyte in a lead storage battery is not hydrochloric acid, but rather a solution of sulfuric acid and water. Sulfuric acid is used as the electrolyte in the lead-acid battery to facilitate the electrochemical reaction that generates the electrical current.
