Liukenemattomia

Liukenemattomia is a Finnish term describing substances that do not dissolve in a given solvent. In practice, it is most often used to refer to insoluble substances in water at a specified temperature, though solubility depends on the solvent and conditions.

Insolubility is a characteristic property: a liukenematon substance forms a heterogeneous mixture or suspension rather than a uniform solution when added to the solvent. Solubility is influenced by factors such as temperature, pressure, and the presence of other dissolved substances. Some materials are insoluble in water or only sparingly soluble, such as sand (silicon dioxide) and many metal oxides; oils are also immiscible with water.

Common examples of liukenemattomia aineita in water at room temperature include sand, quartz, and many metal oxides. Some substances that are not truly insoluble may be described as sparingly soluble (for example, calcium carbonate). The concept is often taught in chemistry and environmental science to distinguish materials that remain solid from those that form solutions.

Applications and implications: Liukenemattomia substances can be separated from liquids by methods such as filtration, decanting, or centrifugation. They influence processes like water treatment, where solids are removed from water, and they affect environmental concerns such as sedimentation and turbidity in natural waterways.
