Redox Titration Curve

Consider the titration of 100.00 mL of 0.0100 M Ce4+ in 1.00 M HClO4 by 0.0400 M Cu+  to give Ce3+ and Cu2+.

Cu2+  + e-  ⇄ Cu+        E° = +0.161 V

Ce4+  + e-  ⇄ Cu3+       E° = +1.700 V (in 1.00 M HClO4)

a) Which ion undergoes oxidation? 

b) Which ion undergoes reduction? 

c) Which of the following is the overall standard reaction?

a. Ce3+  +  Cu2+  ⇄  Ce4+  +  Cu+

b. Ce4+  +  Cu+  ⇄  Ce3+  +  Cu2+

c. Ce4+  +  Cu2+  ⇄  Ce3+  +  Cu+

d. Ce3+  +  Cu+  ⇄  Ce4+  +  Cu2+

d) What is the overall standard potential for this titration (E°cell)?
