Ion-selective electrode potentiometry
Did you know?
WebIon-selective electrodes are used as sensors in potentiometry to measure the potential of a solution when no current is flowing through the circuit. These electrodes are highly selective due to the presence of a selective membrane. This membrane allows only … WebIn reality, ion-selective electrodes can experience interferences by responding to the presence of other ions. Although the fluoride electrode comes close, no membrane is 100% specific for only one ion. Equation 4 assumes that all of the electrode response (E …
Webglass electrode used for pH measurements and ion-selective electrodes used for a variety of ionic analytes such as sodium, potassium, calcium, sulfide, etc. Relationships between electrode potential and concentration are described by the Nernst equation (see text). Potentiometry is frequently used in one of two modes, namely a direct-measurement Web28 nov. 2024 · Solid contact ion selective electrodes are extensively utilized owing to their marvelous performance over traditional liquid contact ones. The main drawback of those solid contact electrodes is aqueous layer formation which affects their constancy. Herein and to overcome this common drawback, a carb …
