What is the overall cell reaction in a lead storage battery during use?

Options

  1. APb(s) + PbO 2 (s) + 2H 2 SO 4 (aq) → 2PbSO 4 (s) + 2H 2 O(l)
  2. BPbSO 4 (s) + 2H 2 O(l) → Pb(s) + PbO 2 (s) + 2H 2 SO 4 (aq)
  3. CPbO 2 (s) + 2H 2 SO 4 (aq) → Pb(s) + PbSO 4 (s) + 2H 2 O(l)
  4. DNone of the above

Correct answer

A. Pb(s) + PbO 2 (s) + 2H 2 SO 4 (aq) → 2PbSO 4 (s) + 2H 2 O(l)

Step-by-step solution

The overall cell reaction in a lead storage battery during use is:Pb(s) + PbO 2 (s) + 2H 2 SO 4 (aq) → 2PbSO 4 (s) + 2H 2 O(l).
