MHT CET 2023 Chemistry question

Identify the overall oxidation reaction that occurs in lead storage cell during discharge?

(A)
(B)
(C)Correct
(D)

Answer: (C)

Solution

During discharge the lead storage cell acts as a galvanic cell. At the anode lead is oxidised: \mathrm{Pb(s) + SO_4^{2-}(aq) \to PbSO_4(s) + 2e^-} (oxidation, loss of electrons, Pb from 0 to +2); at the cathode is reduced: . So the
