Question

During the charging of lead storage battery, the reaction at
anode is represented by :
(a) Pb²⁺ + SO₄²⁻ → PbSO₄
(b) PbSO₄ + 2H₂O → PbO₂ + SO₄²⁻ + 4H⁺ = 2e⁻
(c) Pb → Pb²⁺ + 2e⁻
(d) Pb²⁺ + 2e⁻ → Pb

Answer 1

Explanation:

Cell reaction during discharge =pbO2 + 4H+ SO4²- +2e = PbSO4 +2H2O

Cell reaction during charging phase= 2PbSO4 + 2H2O = Pb + PbO2 + 4H+ 2SO4²-

Answer 2

During the charging of lead storage battery, the reaction at  anode is represented by

PbSO₄ + 2H₂O → PbO₂ + SO₄²⁻ + 4H⁺ = 2e⁻.

Explanation:

• The chemical reaction is  PbSO₄ + 2H₂O → PbO₂ + SO₄²⁻ + 4H⁺ = 2e⁻
• Lead storage battery also known as lead acid batteries.

• In less period it can store more charges and provided high current.
• It is mainly used in cars for recharging.
• In the state of charging, negative plates contained from the cell are lead and positive plates are lead oxide which is an electrolyte of sulfuric acid.
• Electrons removed from the positive plate done by force and using source of charge negative plate is done by the force.
• While charging the battery the reaction is reversed and PbSO₄ converts cathode as PbO₂ and an anode as Pb.
