otopljene

Otopljene is a participial adjective form used in Bosnian, Croatian, and Serbian, derived from the verb otopiti, meaning to melt or to dissolve. As a modifier, otopljene describes substances that have undergone dissolution in a solvent or, in some contexts, materials that have been melted by heating. The form agrees with feminine plural or neuter plural nouns, for example otopljene tvari (dissolved substances) or otopljene mase (melted masses).

In scientific and technical language, otopljene is most commonly encountered to denote substances that are dissolved in a liquid. Common phrases include otopljene soli (dissolved salts) or otopljene tvari u otopini (substances in solution). The term is widely used in chemistry, environmental science, and related fields to describe the state of a solute after dissolution.

The word also appears in contexts referring to melting due to heat, though in metallurgy or materials science the phrase rastopljene mase (melted masses) or similar formulations may be preferred. The general sense depends on context: a solution contains otopljene substances; a metal or polymer may be described as otopljene when it has been melted.

Etymology and related forms: otopljene comes from otopiti (to melt or dissolve) with a prefix o- and the adjectival suffix -ene. Related terms include otopljenje (dissolution or melting process) and rastopiti (to melt or dissolve, often used for processes that melt rather than dissolve). The concept is closely tied to the broader idea of solubility and phase changes in chemistry.
