The reduction potential of the two half cell reactions (occuring in an electrochemical cell) are
PbSO4 + 2e– → Pb + \(\mathrm{SO}_{4}^{2-}\)(Eº = – 0.31 V)
Ag+ (aq) + e– → Ag (s) (Eº = 0.80 V)
The feasible reaction will be
PbSO4 + 2e– → Pb + \(\mathrm{SO}_{4}^{2-}\)(Eº = – 0.31 V)
Ag+ (aq) + e– → Ag (s) (Eº = 0.80 V)
The feasible reaction will be
- Pb + \(\mathrm{SO}_{4}^{2-}\) + 2 Ag+ (aq) → 2 Ag (s) + PbSO4
- PbSO4 + 2 Ag+ (aq) → Pb + \(\mathrm{SO}_{4}^{2-}\)+ 2 Ag (s)
- Pb + \(\mathrm{SO}_{4}^{2-}\)+ Ag (s) → Ag+ (aq) + PbSO4
- PbSO4 + Ag (s) → Ag+ (aq) + Pb + \(\mathrm{SO}_{4}^{2-}\).
Answer
(A) Pb + SO _ 4 ^ 2- + 2 Ag + (aq) → 2 Ag (s) + PbSO 4
