pitoisuuksiksi

Pitoisuuksiksi is the translative plural form of the Finnish noun pitoisuus, meaning concentration. It is used to express becoming into, or designating something as, concentrations, and it appears mainly in scientific and technical writing. The related forms include pitoisuudeksi (singular translative), pitoisuudet (plural nominative), and pitoisuuksiksi (plural translative).

In practice, pitoisuuksiksi is often found in noun phrases that describe values or classifications defined as concentrations. For example, "Näytteen pitoisuuksiksi määritetyt arvot olivat 3,2 prosenttia" translates to "the values defined as the sample’s concentrations were 3.2 percent." Another common usage is in phrases like "pitoisuuksiksi lasketut määrät," meaning amounts calculated as concentrations, or "pitoisuuksiksi ilmoitetut arvot," meaning values reported as concentrations.

Usage notes include that the translative plural form is relatively specialized and commonly seen in technical texts such as reports, lab analyses, and patents. It contrasts with the singular translative pitoisuudeksi, which would be used when referring to a single concentration. The possessive and case forms of related words follow normal Finnish grammar, with the translative suffix -ksi forming the base into a state or category (plural here as -uksiksi) rather than a simple plural noun.

Etymologically, pitoisuuksiksi is built from pitoisuus plus the translative suffix -ksi, with the plural ending indicating multiple concentrations. The term remains largely confined to contexts dealing with chemical concentrations, solution analysis, and related measurements.
