elektrolyüsilises

Elektrolyüsilises, often referred to as electrolysis, is a process that uses a direct electric current to drive an otherwise non-spontaneous chemical reaction. It involves passing an electric current through a substance, typically a molten salt or an aqueous solution, which contains mobile ions. These ions are then attracted to electrodes with opposite charges, leading to chemical changes at the electrode surfaces.

The setup for electrolysis requires an electrolyte, which is the substance containing the ions, and two electrodes, an anode (positively charged) and a cathode (negatively charged). These electrodes are immersed in the electrolyte and connected to a DC power source. At the anode, oxidation occurs, meaning a substance loses electrons. At the cathode, reduction occurs, where a substance gains electrons.

Common applications of electrolysis include the production of various chemical elements and compounds. For instance, it is used to extract reactive metals like aluminum and sodium from their ores. Electrolysis is also fundamental in electroplating, a process used to coat one metal with a thin layer of another for decorative or protective purposes. Furthermore, it plays a role in water splitting to produce hydrogen and oxygen gases, and in the refining of metals like copper. The efficiency and outcome of electrolysis depend on factors such as the nature of the electrolyte, the electrode materials, and the applied voltage.
