Rozpustných

Rozpustných is the genitive plural form of the Czech adjective rozpustný, meaning soluble or dissolvable. It is used to describe substances that can dissolve in a solvent, most commonly water.

In scientific and technical contexts, rozpustný describes the ability of a substance to enter into solution. The corresponding noun is rozpustnost (solubility). The form rozpustných appears after a noun in genitive plural, for example: „většina rozpustných látek“ (the majority of soluble substances) or „počet rozpustných látek“ (the number of soluble substances).

Etymology: rozpustný is derived from the verb rozpustit (to dissolve) with the prefix roz- and the adjectival suffix -ný. The meaning is “capable of being dissolved.”

Morphology and usage notes: As a Czech adjective, rozpustný inflects for gender and number; its genitive plural form is rozpustných. It is commonly encountered in scientific prose, chemistry texts, and data tables discussing solubility, where substances are classified as rozpustných or insoluble.
