tilittivät

Tilittivät is a Finnish word that translates to "they titrated" in English. Titration is a common laboratory method used in chemistry to determine the concentration of an unknown solution. This is achieved by reacting the unknown solution with a solution of known concentration, called a titrant. The titrant is added gradually from a burette until the reaction is complete, which is usually indicated by a color change in an indicator. The volume of titrant used is then measured, and this information, along with the known concentration of the titrant, allows for the calculation of the unknown concentration of the analyte.

The word "tilittivät" specifically refers to the past tense plural form of the verb "titrata," meaning "to titrate." Therefore, it would be used in a sentence describing an action that multiple subjects performed in the past, such as "Kemistit tilittivät näytettä" (The chemists titrated the sample). Titration is a fundamental technique in analytical chemistry and is applied in various fields, including pharmaceuticals, environmental monitoring, and food analysis, for quality control and research purposes. The accuracy of titration relies heavily on precise measurements of volumes and careful observation of the endpoint.
