Elektroanalyysiin

Elektroanalyysiin is a Finnish word that translates to "electrolysis" in English. Electrolysis is a process that uses a direct electric current to drive an otherwise non-spontaneous chemical reaction. In essence, it is the decomposition of a substance by means of an electric current.

This process typically involves submerging two electrodes, an anode and a cathode, into an electrolyte. The electrolyte is a substance that contains free ions and is thus electrically conductive. When an electric current is passed through the electrolyte, the ions are attracted to the electrode with the opposite charge. At the electrodes, chemical reactions occur, leading to the decomposition or synthesis of substances.

Electrolysis has numerous applications in various industries. For example, it is used in the production of many metals, such as aluminum, copper, and sodium. It is also employed in electroplating, a process used to coat one metal with another for decorative or protective purposes. In chemistry, electrolysis is a fundamental technique for both analytical purposes and for synthesizing new compounds. The principles of electrolysis are also crucial in understanding electrochemical cells, including batteries and fuel cells. The specific reactions and outcomes of electrolysis depend on the substance being electrolyzed, the electrodes used, and the applied voltage.
