A cell is set up with copper as well as lead electrodes in contact with CuSO4 (aq,1.0 M) and Pb (NO3)2 (aq, 1.0 M), respectively, at 25°C. Explain the standard cell potential is 0.47 V for the reaction: Cu2+ + Pb --> Cu + Pb2+
Explain if solid sodium sulfate is added to the Pb (NO3)2 solutions, a precipitate of PbSO4 will form. Utilizing the Nerst equation to predict how the cell potential will change.
