WebPotentiometry. Potentiometry, also known as potentiometric titration, is a technique used to determine the potential of an analyte. Also, the amount of analyte is determined by adding titrants of known concentration till the endpoint. Potentiometric titrations can be divided into 4 categories based on the type of reaction taking place. WebIn electrochemistry, chronoamperometry is an analytical technique in which the electric potential of the working electrode is stepped and the resulting current from faradaic processes occurring at the electrode (caused by the potential step) is monitored as a function of time. Web4 Jun 2024 · The equivalence point in a potentiometric titration is usually determined by finding, in some way or other, the point of maximum slope (inflexion point) of the titration curve [10]. In many instances there are very sharp breaks in titration curves, and then, there is no difficulty in finding the equivalence point. shri ram education trust
