A voltaic cell consists of a Pb/Pb2+ half-cell and a Cu/Cu2+ half-cell at 25 âC . The initial concentrations of Pb2+ and Cu2+ are 5.30Ã10â2 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 0.370 V ?
