A voltaic cell consists of a Pb/Pb 2+ half-cell and a Cu/Cu 2+ halfcell at 25 C.

Question:

A voltaic cell consists of a Pb/Pb2+ half-cell and a Cu/Cu2+ halfcell at 25 °C. The initial concentrations of Pb2+ and Cu2+ are 0.0500 M and 1.50 M, respectively.

a. What is the initial cell potential?

b. What is the cell potential when the concentration of Cu2+ has fallen to 0.200 M?

c. What are the concentrations of Pb2+ and Cu2+ when the cell potential falls to 0.35 V?
