Question

Write the reaction taking place at anode and cathode in lead storage battery when it is in use

Answer 1

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

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

Answer 2

HEYA!!!


HERE IS YOUR ANSWER,


FIRSTLY,

⇒ A lead storage battery is an example of SECONDARY CELL.


NOW, THE REACTIONS AT ANODE AND CATHODE ARE :
⇔  AT ANODE,

⇒ Pb (s) + SO₄ → PbSO₄ (s) + 2e⁻


⇔  AT CATHODE,

⇒ PbO₂ (s) + 4H⁺ + SO₄²⁻ + 2e⁻ → PbSO₄ (s) + 2H₂O.


HOPE IT HELPS YOU,
THANK YOU. ^_^
