Theories of the "dead-stop" end-point method of titration of Foulk and Bawden have been studied recently by Delahay, Kies, Duyckaerts, Gauguin and Charlot, and Bradbury, but no conclusive remarks have been obtained by these authors as to the choice of optimum experimental conditions such as the applied voltage, the initial concentration of the solution to be titrated, the temperature, the electrode area, the stirring rate, the resistance in the circuit and the sensitivity of the galvanometer.This situation has handicapped the wide applicability of this method, although it yields accurate results and requires only inexpensive equipment.
