TITRIMETRIC ANALYSIS
UNIT-6 TITRIMETRIC ANALYSISYOU are already aware that a substance is analysed to establish its qualitativeand quantitative chemical composition. Thus, chemical ANALYSIS can becategorised as qualitative ANALYSIS and quantitative ANALYSIS . In this unityou will learn about determination of the amount of substance in solution. Dependingupon the method adopted for determining the amount of chemical substances insolution, there are two methods of ANALYSIS namely, TITRIMETRIC ANALYSIS andgravimetric ANALYSIS . In TITRIMETRIC ANALYSIS measurement of only volumes is involvedwhile in gravimetric ANALYSIS measurement of volumes as well as mass is ANALYSIS involves determination of the volume of a solution ofaccurately known concentration, which is required to react quantitatively withthe measured volume of the solution of a substance, concentration of which is tobe determined.
used for standardization after finding out its exact concentration by titration against a standard solution of primary standard. A secondary standard cannot be used for preparing standard solution by direct weighing. Sodium hydroxide and potassium permanganate are examples of secondary standards.
