Used as a reference electrode in electrochemical measurements due to its stable and reproducible potential. Commonly applied in cathodic protection systems to monitor the effectiveness of corrosion control on pipelines, tanks, and marine structures. Also utilized in agriculture to correct copper deficiencies in soils and as a fungicide in vineyards and farms. In laboratories, serves as a standard solution for calibrating pH meters and conducting redox titrations. Additionally, employed in educational settings to demonstrate crystal growth and electroplating processes.
