Question:

An electrochemical cell is composed of pure copper and pure lead electrodes immersed in solutions of their respective divalent ions. For a 0.6 M concentration of Cu2+, the lead electrode is oxidized yielding a cell potential of 0.507 V. Calculate the concentration of Pb2+ ions if the temperature is 25°C.
