Titrimetric Methods of Analysis
Lecture Two covers the following points:-
- Titrimetric Methods
- -Some General Aspects
-Definition of Some Terms
Titrimetric methods include
a large and powerful group of quantitative procedures that are based upon measuring the amount of reagent of known concentration that is consumed by the analyte.
Volumetric titrimetry involves measuring the volume of a solution of known concentration that is needed to react essentially completely with the analyte.
Titrimetric methods are widely used for
routine analyses because they are rapid, convenient, accurate and readily automated.
Titration:
It is a process where Titrant slowly add to Analyte until the reaction between the two solution is judged complete
The volume of reagent needed to complete the titration is determined from the difference between the initial and final volume readings
Equivalence point
This point in a titration is reached when the amount of added titrant is chemically equivalent to the amount of analyte in the sample.
It is a theoretical point that cannot be determined experimentally.
End Point:
It is the point at which physical change associated with the condition of equivalence.
Titration Error
The difference in volume between the equivalence point and the end point
Indicator
They are reagents often added to the analyte solution in order to give an observable physical change at the end point or near the equivalence point.
