Questions

1. Determine the correct Ecell for each reaction. 
 
2. Give one possible reason why the two Ecell are not the same. 
 
3. What the unknown metal and justify your answer. 
 
4. Draw the electrochemical cell with all appropriate information for the copper concentrated cell (Hint you need to do Nernst Equ.) 
 
5. Draw the electrochemical cell with all appropriate information for the lead concentrated cell (Hint you need to do Nernst Equ.). 
a. Use the cell potential for Pb-<nowiki>PbI</nowiki>2 cell and the known [Pb2+] in equilibrium with <nowiki>PbI</nowiki>2 
b. Use the original dilute [Pb2+] and [I1-] to calculate the [I1-] in solution. 
c. Using your data to calculate the Ksp of <nowiki>PbI</nowiki>2. 
d. The accepted value of the Ksp of <nowiki>PbI</nowiki>2 is 9.8E-9. How does your experimental results compared to the accepted value.
