CHEM 162 NAME ________________________________ Electrochemistry II SECTION _____________________________ PRE-LAB EXERCISE 1. Calculate ∆E0 for the reactions listed below. Reaction ∆E0 Cu + 2Ag+ --> Cu2+ + 2Ag Pb + 2Ag+ --> Pb2+ + 2Ag Zn + 2Ag+ --> Zn2+ + 2Ag Sn + 2Ag+ --> Sn2+ + 2Ag Zn + Pb2+ --> Zn2+ + Pb 2. What would be the potential of the cell Cu/Cu2+(0.1M)//Cu2+(1.0M)/Cu? Ecell = 3. From the potentials you calculated in question #1 or from standard reduction potentials what two half-cells would you combine to make a galvanic cell that produces a voltage of 0.627V? oxidation half-cell is reduction half-cell is
