Calculations:
Three voltaic cells were constructed from solutions of CuSO4(aq), ZnSO,(aq), and Pb(NO3)2(aq) and the
corresponding metal electrodes.
1. For each combination of solutions, calculate the standard cell potential, E°cell- Remember that for a
spontaneous reaction, E°cell must be positive when E°anode is subtracted from E°cathode-
a. Cu/Zn
b. Cu/Pb
