elektroreaktiot

Elektroreaktiot, often translated as electroreactions, refers to chemical reactions that are driven or influenced by electricity. This encompasses a broad range of phenomena where electrical energy is used to initiate, accelerate, or control chemical transformations, or conversely, where chemical reactions generate electrical energy.

A primary example of electroreactions is electrolysis. In this process, an electric current is passed through an electrolyte, a solution or molten substance containing ions. The electrical energy causes a non-spontaneous chemical reaction to occur. This is used in various industrial applications, such as the production of aluminum, chlorine, and hydrogen, as well as in electroplating to coat objects with a thin layer of metal.

Another significant category is electrochemical cells, which can be either galvanic (voltaic) cells or electrolytic cells. Galvanic cells, like batteries, convert chemical energy into electrical energy through spontaneous redox (reduction-oxidation) reactions. Electrolytic cells, as mentioned with electrolysis, use electrical energy to drive non-spontaneous redox reactions.

Electroreactions are fundamental to understanding processes like corrosion, where electrochemical reactions cause the degradation of materials. They are also crucial in biological systems, for instance, in nerve impulse transmission and cellular respiration, where electron transfer reactions are vital. The study and application of electroreactions are central to the field of electrochemistry.
