Abstract

Analytical chemistry, a branch of chemistry, deals with the analysis of
substances. Identification of the constituents from the mixture or substance is called
qualitative analysis while Quantitative Analysis deals with determining the purity of
the constituents present in the mixture. This is also known as assay method. Various
methods like volumetric analysis, gravimetric analysis, polarimetry, refractometry,
photometry, fluorimetry, electrochemical methods, chromatographic methods and
biological methods comes under the category of quantitative analysis. Volumetric
titrations are the elementary procedures applied in the life sciences, pharmaceutics,
industrial analysis, water pollution and clinical chemistry and are used to determine the
amount of analyte with the standard solution. Main advantages of these methods are
cost-effective, rapid and simple, while disadvantages include pH, temperature, and
humidity sensitivity, indicator requirement, occurrence of human error, etc.


Keywords: Analytical chemistry, Endpoint, Indicator, Quantitative analysis, Volumetric titration.
