roztworom

Roztworom is the dative plural form of the Polish noun roztwór, meaning "solution" or "mixture" depending on context. In Polish grammar, roztwór is a masculine noun of the second declension; its plural forms include roztwory (nominative), roztworów (genitive), roztworom (dative), roztwory (accusative), roztworami (instrumental), and roztworach (locative). Therefore roztworom is used when referring to “to/for the solutions” in sentences that require a plural indirect object.

In scientific usage, roztwór denotes a homogeneous phase formed by dissolving solutes in a solvent. Common examples are aqueous solutions such as saline solution or sugar in water. Characteristics of roztwory include concentration, which can be described by molarity, molality, or mass percent; properties such as conductivity and colligative effects depend on the amount of solute dissolved.

The term roztworom appears primarily in grammatically technical contexts (linguistics and translation) when constructing sentences that take a dative plural object. In everyday Polish, speakers typically refer to roztwory for the plural “solutions” and reserve roztworom for sentences that require a dative plural object.
