Chapter 24, Problem 24-12(choose chapter or problem)
Construct a eoulometric titration curve of 100.0 mL of a I M H,S04 solutioncontaining Fe(lI) titrated with Ce(IV) generated from 0.075 M Ce(III). Thetitration is monitored by potentiometry. The initial amount of Fe(lI) present is0.05182 mmol. A constant current of 20.0 mA is used. Find the time correspondingto the equivalence point. Then, for about ten values of time before theequivalence point, use the stoichiometry of the reaction to calculate the amountof Fe" produced and the amount of Fe'+ remaining. Use the Nemst equationto find the system potential. Find the equivalence point potential in the usualmanner for a redox titration. For about ten times after the equivalence point,calculate the amount of Ce 4+produced from the electrolysis and the amount ofCe 3+ remaining. Plot the curve of system potential versus electrolysis time.
