Feloldódik

Feloldódik is a Hungarian verb meaning "to dissolve" or "to become dissolved." It describes the process by which a substance disperses in a solvent until a homogeneous phase is formed. A typical usage is exemplified by the sentence: a konyhasó feloldódik a vízben.

In chemistry, dissolution is the process by which solute particles separate and are surrounded by solvent molecules, resulting in a solution. The rate and extent of dissolution depend on several factors, including temperature, the nature of the solvent (polarity and ability to form favorable interactions), particle size, and agitation. Solubility refers to the maximum amount of solute that can dissolve at a given temperature, while the dissolution rate describes how quickly this process occurs. At equilibrium, a solution can be saturated, unsaturated, or supersaturated, with undissolved solute present in a saturated system and potentially precipitating if conditions change.

Temperature has a characteristic effect: for most solid solutes in liquids, solubility increases with rising temperature; for most gases, solubility decreases as temperature rises. Pressure mainly influences the solubility of gases in liquids. Dissolution can be endothermic or exothermic, depending on the specific interactions between solute and solvent.

Common examples include dissolving table salt or sugar in water, or medications dissolving in bodily fluids. Understanding dissolution is important across chemistry, pharmacology, environmental science, and food technology, where the rate and extent of dissolution affect effectiveness, stability, and behavior of substances in solutions.
