In this experiment, we will use the electrochemical cell as a method of chemical analysis called potentiometric titration. A potentiometric titration is similar to the acid-base titrations you have performed; however, the means of determining the concentration of a species is dependent upon an oxidation-reduction reaction rather than a ...
As shown in Figure 11.3, we use a potentiometer to determine the difference between the potential of two electrodes. The potential of one electrode—the working or indicator electrode—responds to the analyte’s activity, and the other electrode—the counter or reference electrode—has a known, fixed potential.
Determination of Chloride using Potentiometry - Chemistry ...
This procedure will determine the concentration of chloride ion with a chloride specific ion electrode using potentiometry. 2. Background. Potentiometry is an electrochemical method in which the potential of an electrochemical cell is measured while little to no current is passed through the sample.
Experiment 17: Potentiometric Titration - Boston College
Experiment 17: Potentiometric Titration. Objective: In this experiment, you will use a pH meter to follow the course of acid-base titrations. From the resulting titration curves, you will determine the concentrations of the acidic solutions as well as the acid-ionization constant of a weak acid.
Chapter 21 Potentiometry - University of Southern Mississippi
Definition. Potentiometric methods are based upon measurements of the potential of electrochemical cells in the absence of appreciable currents. an equilibrium measurement. the Nernst equation is applicable.
4.04 REDOX POTENTIALS FROM POTENTIOMETRIC TITRATIONS
This experiment is an exercise in simple equilibrium electrochemistry. In it, you will first investigate the Fe3+ / Fe2+ redox couple by performing an electrochemical titration with Ce4+. This requires the generation of an electrode potential which is monitored as the titration proceeds.
