Titrimetric Analysis: Methods

Titrimetric Analysis: MethodsTitrimetric Methods of analysis are capable of rapid and convenient analyte determinations with highaccuracy and precision. Titrimetric analysis is based on the complete reaction between the analyte anda reagent, the titrant:aA + tT t productswhere A and T represent the analyte and titrant, respectively, and a and t are the stoichiometriccoefficients. Titrations are often classified by the nature of this titration reaction: acid-base, redox,precipitation and complexation reactions are the most common reaction volumetric titrations, the amount, nA, of analyte in the sample can be calculated usingnA=atCTVT where CT is the concentration of the titrant, and VT is the volume of titrant needed to reach theendpoint. Thus, quantitative determination of the analyte concentration requires the following:1.

detection of interferences. In this document, we will examine some of the specifics of titrimetric analysis: the most common titrants and the types of analytes they react with, methods of titrant standardization, the stability of titrant solutions, methods of endpoint detection, and any other details that might be important.

2. Spectrochemical methods of analysis, in which the analyte interacts with electromagnetic radiation. Most of the methods in this category are based on the measurement of the amount of light absorbed by a sample; such absorption-based techniques include atomic absorption, molecular absorption, and nmr methods.
