Abstract. While pH electrodes are much more commonly used to monitor the progress of strong acid – strong base titrations, an electrical conductance sensor is shown to provide a more accurate indication of the location of the equivalence point and to do so at much higher titrant delivery rates, thereby greatly expediting and otherwise improving the procedure.
