Electrochemical methods are techniques that use electrical energy to drive chemical reactions. These methods are commonly employed in various applications, such as batteries, fuel cells, and electroplating. By applying a voltage, these processes can facilitate the transfer of electrons, leading to the desired chemical changes. In research and industry, electrochemical methods are valuable for analyzing substances and measuring concentrations. Techniques like potentiometry and voltammetry allow scientists to study the properties of materials and monitor reactions in real-time. This versatility makes electrochemical methods essential in fields like environmental science and materials engineering.
