Potentiometric meaning

WebPotentiometry is a technique that is used in analytical chemistry, usually to find the concentration of a solute in solution. In this technique, the potential between two electrodes is measured using a high-impedance voltmeter (Wang, 2000 ). Use of a high-impedance voltmeter ensures that current flow is negligible. WebA potentiometric surface is the imaginary plane where a given reservoir of fluid will "equalize out to" if allowed to flow. A potentiometric surface is based on hydraulic …
