Construct a coulometric titration curve of 100.0 mL of a 1 M H2S04 solution containing Fe (II) titrated with Ce (IV) generated from 0.075 M Ce (III). The titration is monitored by potentiometry. The initial amount of Fe (II) present is 0.05182 mmol. A constant current of 20.0 mA is used. Find the time corresponding to the equivalence point. Then, for about ten values of time before the equivalence point, use the stoichiometry of the reaction to calculate the amount of Fe3+ produced and the amount of Fe2+ remaining. Use the Nernst equation to find the system potential. Find the equivalence point potential in the usual manner for a redox titration. For about ten times after the equivalence point, calculate the amount of Ce4+produced from the electrolysis and the amount of Ce3+ remaining. Plot the curve of system potential versus electrolysis time.
