WebAug 29, 2024 · In analytical chemistry, the titrant is a solution of known concentration that is added ( titrated) to another solution to determine the concentration of a second chemical species. The titrant may also be called the titrator, the reagent, or the standard solution . In contrast, the analyte, or titrand, is the species of interest during a titration. WebThe effective titrant concentration normally differs from the nominal concentration due to either inaccurate preparation, purity of titrant used, or changes due to instability. The effective concentration is determined by means of a titer determination or titration of a substance of exactly known concentration, usually a primary standard.
