WebPotentiometry is a static interfacial method and the most widely used electrochemical method in analytical applications [8]. A notable example of potentiometry is the pH meter (Fig. 6.1), which is usually based on glass membrane electrodes as indicators of the concentration (more accurately, the activity) of the H + ions in solution.

Web1. Purpose. 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. WebVoltammetry is a category of electroanalytical methods used in analytical chemistry and various industrial processes. In voltammetry, information about an analyte is obtained by measuring the current as the potential is varied. The analytical data for a voltammetric experiment comes in the form of a voltammogram which plots the current produced by …
