vesiliuoksissaan

Vesiliuoksissaan is a Finnish expression used to describe a substance as it exists in an aqueous solution. It indicates that the material is dissolved or dispersed in water rather than present as a dry solid or in another phase. The phrase is commonly found in scientific writing, including chemistry, pharmacology, and environmental science, where the behavior of a substance in water is relevant to solubility, reactivity, or stability.

The expression is typically used with the subject of the sentence to denote its state in water. It can be contrasted with references to the pure solid form or to non-aqueous media. In practice, vesiliuoksissaan helps to specify that observations or measurements pertain to the substance in its aqueous form, not to its undissolved solid or other phase.

Examples:

- Natriumkloridi vesiliuoksissaan liukenee nopeasti veteen.

- Tutkimuksessa aine X vesiliuoksissaan osoittaa ionien liikkuvuutta sähkökentän vaikutuksesta.
