A silver/silver chloride electrode is a type of reference electrode commonly used in electrochemical measurements. It consists of a silver wire coated with a layer of silver chloride, which forms a stable and well-defined potential in solution. This electrode is often used in pH meters and other electrochemical sensors due to its reliability and ease of use. The silver/silver chloride electrode operates based on the equilibrium between the silver, silver chloride, and chloride ions in the solution. When immersed in an electrolyte, it maintains a constant voltage, making it an essential component in various scientific and industrial applications, including voltammetry and potentiometry.
