liuosissa

Liuosissa is the Finnish word meaning “in solutions” and is the inessive form of the noun liuos (solution). It is used in chemistry and related disciplines to describe the state of substances that have dissolved in a solvent, typically water or another liquid. The term signals that the described substances exist within a solution rather than as a separate phase.

A solution is a homogeneous mixture of a solute dissolved in a solvent. The solvent is the component present in greater amount; the solute is the substance dissolved. Solutions are characterized by their concentration and by properties such as solubility, boiling point, and electrical conductivity. Common ways to express concentration include molarity (moles per liter), molality (moles per kilogram of solvent), and percent by mass or volume.

Dissolution depends on several factors. Temperature and agitation can accelerate the process, while particle size and surface area influence how quickly solutes dissolve. The principle “like dissolves like” describes how polar solvents tend to dissolve polar solutes and nonpolar solvents tend to dissolve nonpolar solutes. Solubility is specific to a given solute–solvent pair and can be affected by pressure for gaseous solutes.

In Finnish texts, liuosissa denotes “in solutions” and is used when multiple solutions or a general state of being dissolved in a liquid is described. It appears in scientific writing to specify that substances are present within the liquid phase rather than as a separate solid or gas. Related terms include liuos (solution), liuotin (solvent), and liuottaminen (dissolution).
