Lahustatud

Lahustatud is an Estonian adjective meaning dissolved or solubilized. It describes a substance that has been dissolved in a solvent to form a solution. The word is the past passive participle derived from the verb lahustada (to dissolve) and functions as an adjective in sentences such as "lahustatud sool" (dissolved salt). The corresponding opposite term is lahustamata, meaning undissolved. The related noun for the process is lahustamine, or dissolution.

In scientific and technical contexts, lahustatud is used to distinguish the dissolved state from solid, undissolved material. For example, a substance may be described as lahustatud in water, indicating that it has dispersed at the molecular or ionic level throughout the solvent. The term is common in chemistry, environmental science, water quality, and materials science. Measurements of dissolved substances often appear as dissolved solids or dissolved load, concepts that rely on the idea of something being lahustatud rather than suspended or precipitated.

Related concepts include solubility (the capacity of a substance to become lahustatud in a solvent), solution (the resulting homogeneous mixture), solvent, and solute. While lahustatud translates roughly to dissolved in everyday language, it is primarily a technical descriptor used to specify the state of a substance within a solution rather than its general properties as a solid or powder.
