Introduction to Volumetric Analysis
soe.unipune.ac.inVolumetric analysis Volumetric analysis is also known as titrimetric analysis. The reagent (the titrant) is added gradually or stepwise to the analyte from a burette. The key to performing a successful titrimetric analysis is to recognize the equivalence point of the titration (the point at which the quantities of the two reacting species are equivalent), typically observed as
