|
Volumetric Analysis
|
a technique in which the volume of material needed to react with the analyte is measured
|
|
|
Titration
|
a procedure in which one substance (titrant) is carefully added to another (analyte) until complete reaction has occurred. The quantity of titrant required for complete reaction tells how much analyte is present.
|
|
|
Equivalence Point
|
in a titration when all analyte has reacted and there is no excess titrant
|
|
|
End Point
|
when a titration is stopped, recognized by a sudden change in a physical property of the solution
|
|
|
Indicator
|
a compound with a physical property (usually color) that changes abruptly near the equivalence point
|
|
|
Titration Error
|
the difference between the end point and the equivalence point
|
|
|
Blank Titration
|
a titration is carried out without analyte to estimate titration error
|
|
|
Primary Standard
|
a solution that can be readily obtained in high purity and low cost
|
|
|
Secondary Standard
|
a solution whose makeup is determined by reference to a primary standard
|
|
|
Direct Titration
|
titrant is added to analyte until the reaction is complete
|
|
|
Back Titration
|
an excess of standard reagent is added to react with analyte, then the excess reagent is titrated with a second reagent
|
|
|
Kjeldahl Nitrogen Analysis
|
procedure for the analysis of nitrogen in organic compounds
|
|
|
Spectrophotometric Titration
|
titration in which absorption of light is used to monitor the progress of the reaction
