Electrochemical analysis is a technique used to study the chemical properties of substances by measuring their electrical characteristics. This method involves applying a voltage to a solution and observing the resulting current, which can provide information about the concentration and type of chemical species present. Common techniques include potentiometry, voltammetry, and amperometry. This analysis is widely used in various fields, including environmental monitoring, pharmaceuticals, and food safety. By understanding the electrochemical behavior of different compounds, scientists can develop sensors and methods for detecting pollutants, ensuring product quality, and conducting research in biochemistry and materials science.
