nierozpuszczonej

Nierozpuszczonej is the genitive singular feminine form of the Polish adjective nierozpuszczony, which means undissolved or not dissolved. The base form nierozpuszczony is built from the negation prefix nie- and the verb rozpuścić (to dissolve). Like other adjectives and participles, nierozpuszczony declines by gender, number, and case, so nierozpuszczonej is used specifically when describing a feminine noun in the genitive case, for example in phrases such as cząstki nierozpuszczonej soli (undissolved salt particles).

In scientific and technical usage, nierozpuszczonej typically appears in discussions of solubility, mixtures, and suspensions. It denotes the portion of a substance that has not dissolved in a solvent, forming a solid phase or solid impurities within a liquid. This distinction between dissolved and undissolved components is central to analyses in chemistry, materials science, environmental science, and related fields. The term helps describe problems such as precipitation, sedimentation, or the presence of insoluble residues after a reaction or filtration.

Usage notes: nierozpuszczonej is a grammatical form used when the feminine noun it modifies is in the genitive case. The concept it expresses can be conveyed with related terms such as nierozpuszczalny (insoluble) or rozpuszczony (dissolved), but nierozpuszczonej specifically emphasizes the undissolved state of a substance within a particular context. Examples include sentences about undissolved solids in a solution or insoluble fractions remaining after processing.
