Answer to Question #350296 in General Chemistry for Ruth

Question

Consider the potentiometric titration of 100.0 mL of 0.0100M Ce 4+in 1M HClO 4by

0.0400M Cu + to give Ce 3 + and Cu 2 + using Pt and saturated Ag|AgCl electrodes to find the end point. ( 15 marks)

a. Write a balanced titration reaction.

b. Write two different half-reactions for the indicator electrode.

c. Write two different Nernst equations for the cell voltage.

d. Calculate E at the following volumes of Cu + : 1.00, 12.5, 24.5,

25.0, 25.5, 30.0, and 50.0 mL. Sketch the titration curve
