Titriert

Titriert is the past participle of the German verb titrieren, meaning to perform a titration. In chemistry, titration is a quantitative analysis method used to determine the concentration of an unknown solution by reacting it with a solution of known concentration (the titrant) until the reaction reaches its end point. A solution that has undergone titration or a sample whose concentration has been established by titration is described as titriert.

In a typical titration, a burette delivers the titrant into the analyte under study while monitoring the reaction progress. The end point is the observable moment when the signal indicates that the reaction has reached its completion, such as a color change produced by an indicator or a stable change in measured electrode potential or pH. The equivalence point, a theoretical concept, is the point at which the reactants have reacted in their exact stoichiometric ratio. In many cases the end point is chosen to approximate the equivalence point.

Common types of titration include acid-base titration, redox titration, complexometric titration, and precipitation titration. Calculations after titration relate the known concentration and volume of the titrant to the unknown concentration of the analyte, typically via the stoichiometric equation: c_analyte × V_analyte = c_titrant × V_titrant × (stoichiometric factor).

Applications of titration span quality control, pharmaceutical analysis, environmental testing, food chemistry, and educational laboratories. The term titration and its passive form titriert appear widely in German scientific literature and lab reports. See also: endpoint, equivalence point, titration curve, indicator.
