What are the cell reactions when the lead storage battery is in use?

Options

  1. APb(s) + PbO 2 (s) → PbSO 4 (s) + 2H 2 O(l)
  2. BPb(s) + SO 4 2-(aq) → PbSO 4 (s) + 2e-
  3. CPbO 2 (s) + SO 4 2-(aq) + 4H+(aq) + 2e- → PbSO 4 (s) + 2H 2 O (l)
  4. Dboth B and C

Correct answer

D. both B and C

Step-by-step solution

The paragraph provides the cell reactions when the lead storage battery is in use as:Anode: Pb(s) + SO 4 2-(aq) → PbSO 4 (s) + 2e-Cathode: PbO 2 (s) + SO 4 2-(aq) + 4H+(aq) + 2e- → PbSO 4 (s) + 2H 2 O (l)
