Standard Reference Electrode. A standard hydrogen electrode she is an electrode that scientists use for reference on all half cell potential reactions. The value of the standard electrode potential is zero which forms the basis one needs to calculate cell potentials using different electrodes or different concentrations.
Science chemistry electrochemistry reference electrodes. Two commonly used reference electrodes are standard hydrogen electrode she and calomel electrode. A standard reference electrode is also known as a standard hydrogen electrode she.
Using reference electrodes unknown potential of any other single electrode can be found out e g.
Common reference electrodes and potential with respect to the standard hydrogen electrode. The standard hydrogen electrode or she is composed of an inert solid like platinum on which hydrogen gas is adsorbed immersed in a solution containing hydrogen ions at unit activity. A standard reference electrode is an electrode that has a known electrical potential. For potentiometric sensors an accurate and stable reference electrode that acts as a half cell in the measurement circuit is critical to providing a stable reference potential and for measuring the change in potential difference across the ph sensitive membrane as the ph concentration changes.
