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.
Key Words: Laboratories and Demonstrations; analitic chemistry; autotitrimetry; drop counting; conductivity and pH measurement; sensor response lag
