CHEM 162 NAME _____________________________ LABORATORY REPORT SECTION ___________________________ ELECTROCHEMISTRY II Part I: Measurement of Standard Potentials (E ) 1. List the cells you tested in Part I in order of increasing voltage with silver metal as a reactant. Reaction ∆E0 2. Calculate the standard reduction potential for each metal ion give that E0 = 0.80 V for Ag+. Metal ion ∆E0 Cu2+ Pb2+ Zn2+ Sn2+ Ag+ 3. What is the expected cell potential for the Pb/Pb2+(1M)/Zn2+(1M)/Zn cell based on your half- cell potential measurements from question #2? How does this value compare with your actual measurement? 4. Compare your values with those in Table 20.2 (Silberberg, p.891). How do your observed values compare with those of your textbook? If they are off, are they always low or high compared to your textbook? What might be the cause of the difference?
