Which among the following equations represents the reduction reaction taking place in lead accumulator at positive electrode, while it is being used as a source of electrical energy?

Question

Accepted Answer

Correct answer: D. (d): Reactions occurring in lead storage battery during discharging: At anode : Pb_ (s )+ SO_4 ( aq )^2- ⟶ PbSO_4 (s )+2e^- (-ve electrode) At cathode : PbO_2 (s )+ SO_4 ( aq )^2-+4H^++2e^- ⟶ +2 PbSO_4 (s )+2H_2O (-ve electrode)
