WebThe potentiometric principle is most commonly used for automated or semi-automated titrations (manual titration with a sensor and a measuring unit).This includes pH … In analytical chemistry, potentiometric titration is a technique similar to direct titration of a redox reaction. It is a useful means of characterizing an acid. No indicator is used; instead the electric potential is measured across the analyte, typically an electrolyte solution. To do this, two electrodes are used, an … See more The first potentiometric titration was carried out in 1893 by Robert Behrend at Ostwald's Institute in Leipzig.

Web13 Apr 2024 · The endpoint is the point in a titration where the indicator changes color, indicating that the reaction has completed. It is the point where the amount of titrant (the substance being added during the titration) is sufficient to completely react with all of the analyte (the substance being titrated). WebPurpose: The objective of this study was to compare the results of a normal saturation shake-flask method to a new potentiometric acid-base titration method for determining the intrinsic solubility and the solubility-pH profiles of ionizable molecules, and to report the solubility constants determined by the latter technique. Methods: The solubility-pH …
