A voltaic cell is constructed that is based on the following reaction.
Sn2+(aq) + Pb(s) -> Sn(s) + Pb2+(aq)
(a) If the concentration of Sn2+ in the cathode half-cell is 1.80 M and the cell generates an emf of +0.219 V, what is the concentration of Pb2+ in the anode half-cell?


(b) If the anode half-cell contains [SO42−] = 19.08 M in equilibrium with PbSO4(s), what is the Ksp of PbSO4?
