Analyte: An analyte is the sample constituent whose concentration is sought in a chemical analysis.

Titration: A procedure for determining the amount of some unknown substance (the analyte) by quantitative reaction with a measured volume of a solution of precisely known concentration (the titrant).

Titration Curve: A plot that summarizes data collected in a titration. A linear titration curve plots moles of analyte (or, some quantity proportional to moles of analyte) on the Y axis, and the volume of ti . . . View Full Definition

Titrant: The substance that quantitatively reacts with the analyte in a titration. The titrant is usually a standard solution added carefully to the analyte until the reaction is complete. The amount . . . View Full Definition

Limit Of Quantitation: The smallest detectable concentration an analytical instrument can determine at a given confidence level. IUPAC defines the quantitative detection limit as Cld = ks/m, where k is 10, s is th . . . View Full Definition

Back Titration: Determining the concentration of an analyte by reacting it with a known number of moles of excess reagent. The excess reagent is then titrated with a second reagent. The concentration of the . . . View Full Definition

Colorimetry: A method for chemical analysis that relates color intensity to the concentration of analyte.

Equivalence Point: The equivalence point is the point in a titration when enough titrant has been added to react completely with the analyte.
