Elektrolyyttisellä

Elektrolyyttisellä refers to something that is related to electrolysis. Electrolysis is a process that uses a direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. In essence, it is the decomposition of a substance by passing an electric current through it. This substance is typically an electrolyte, which is a solution or molten salt containing free ions.

The fundamental principle behind electrolysis involves the movement of ions under the influence of an electric field. When an electric current is applied to an electrolyte, positively charged ions (cations) migrate towards the negatively charged electrode (cathode), where they gain electrons and are reduced. Conversely, negatively charged ions (anions) move towards the positively charged electrode (anode), where they lose electrons and are oxidized.

Elektrolyyttisellä processes have numerous practical applications. They are widely used in electroplating, a method of coating a thin layer of one metal onto another for decorative or protective purposes, such as in chrome plating. Electrolysis is also crucial in the refining of metals like copper and aluminum, where impure metals are purified to high standards. Furthermore, it plays a role in the production of various chemicals, including chlorine gas and sodium hydroxide. The term elektrolyyttisellä is therefore used to describe apparatus, methods, or phenomena associated with this fundamental electrochemical technique.
