Definitions for "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 of analyte is calculated from the volume of titrant required for complete reaction.
a reagent containing a species that either complexes or liberates the species being determined. An ideal titrant should react instantaneously, completely, and stoichiometrically with the species being determined. The titrant is added in measured increments from a burette and the sample concentration determined from the amount of titrant needed for complete reaction.
a substance used to cause a reaction and detect another substance.
