Solution Summary

This solution shows the calculation of solubility product constant from electrochemical data.

Solution Preview

The oxidation half-reaction of the cell is the oxidation of Pb to Pb2+, and the reduction half reaction is the SHE half reaction.
OHR: Pb(s) <=> Pb2+(aq) + 2e- E° = 0.126 V
RHR: 2H+ + 2e- <=> H2O E° = 0.000 V
