title: Coulometric titration by a controlled-potential pulsed-charge potentiometric technique-II Acid-base, precipitation and homogeneous redox systems.
abstract: An unconventional coulometric method, based on electrolysis at controlled potential by means of discrete charge-pulses, with end-point detection obtained by mathematical linearization of potentiometric data, has been applied to various systems. The results appear very satisfactory: very weak acids can be determined with high accuracy; in the case of precipitation reactions the selectivity is high enough to allow titration of the components of halide mixtures; for homogeneous redox systems some problems caused by irreversibility at the indicator electrode are overcome.
