referensseelektrodiä

Referensselektrodiä refers to a reference electrode in Finnish. A reference electrode is an electrode that has a stable, well-defined, and reproducible electrode potential. It is used in electrochemistry as a point of comparison for measuring the potential of other electrodes or electrochemical systems. The potential of a reference electrode is not affected by the composition of the solution being studied, making it ideal for establishing a consistent electrical reference.

Commonly used reference electrodes include the saturated calomel electrode (SCE) and the silver-silver chloride electrode (Ag/AgCl). These electrodes are constructed in a way that ensures their potential remains constant under various conditions. The stability of the reference electrode's potential is crucial for accurate electrochemical measurements, such as those performed in potentiometry, voltammetry, and electroanalysis. Without a stable reference point, it would be impossible to reliably determine the potential differences that drive electrochemical reactions or indicate the concentration of species in a solution. Therefore, the proper selection and maintenance of a reference electrode are fundamental to experimental success in electrochemistry.
