Abstract. Sensor response lag is a significant problem in autotitrimetry and, for a variety of analyte-titrant combinations, more accurate and more rapidly responsive conductometric monitoring of the progress of their titrations is shown to be preferable to conventional potentiometric sensing of analyte concentrations with a pH electrode.
