Question

Calculate the value of the solubility product constant for PbSO4 from the half-cell potentials.

PbSO4(s) + 2e- → Pb(s) + SO42-(aq) Eº = -0.314 V
Pb2+ + 2e- → Pb(s) Eº = -0.156 V

These half-cell potentials are not accurate. You many imagine that they were determined by a poor experimentalist.
