"Find the Standard Reduction potentials using the Nerst
equation. Ecell are the values given."
Standard Reduction Potentials: Voltaic Cells: Cu-Pb Cu-Al Cu-Fe Measured Cell Potential (V): 1.075 0.482 0.807 0.489 Calculated Standard Reduction Potentials using Cu as the cathode, E° red=0.34V. (Given that concentrations are 0.100M, you will need to use the Nernst equation.) Reduction Reaction Standard Reduction Potential (Measured Value) Cu 2+ (aq) + 2e- --> Cu(s) 0.34 V Zn 2+ (aq) + 2e- --> Zn(s) —— Pb 2+(aq) + 2e- Pb(s) Al3+(aq) + 3e- --> Al(s) Fe3+(aq) + 3e- --> Fe(s) Cu-Zn
