Potentiometric Redox Titration Experiments

Be sure also to look at the bibliography for coulometric titrations! These references are for spontaneous redox processes rather than the forced redox reactions of coulometry.

Automatic potentiometric titrations
Chester A. Pinkham and Brownlee Field
J. Chem. Educ., 1977, 54 (9), p 577

This describes a titration of a mixture of chloride and iodide with a constant flow of AgNO3 solution, following the course of the reaction with a Ag electrode vs. reference electrode. This is easily accomplished with the MicroLab drop dispenser and drop counter along with the FS-522 unit and electrodes plugged into the voltage jack.
