kiválását

Kiválását is a Hungarian noun describing the act or result of separating or precipitating a substance from a mixture or solution. In everyday and scientific language, it most often refers to a solid forming and separating from a liquid (precipitation), but it can also denote any process by which a component becomes distinct or expelled from a system.

Etymology: The term derives from the verb kiválni, formed with ki- meaning “out” and válik meaning “to become,” with the nominal suffix -ás and the inflection -át/-ását used to mark the object of the action.

In chemistry and materials science, kiválást refers to precipitation reactions and the formation of a precipitate. Changes in concentration, temperature, pH, or the presence of competing ions can cause a dissolved substance to precipitate. This process is used in qualitative and quantitative analyses, water treatment, and the purification of chemicals.

In geology and environmental science, minerals and salts can precipitate from fluids such as hydrothermal solutions or evaporating waters, forming crusts, veins, or evaporite deposits. Precipitation also plays a role in karst processes and cave formation.

In everyday language, the term can be used figuratively to describe the emergence, isolation, or separation of a component, feature, or issue from a larger system.
