ABSTRACT
Titration is one of the most commonly employed techniques in wet analysis. Many routine analyses of wastewaters, potable waters, and aqueous extracts of sludges and soils can be effectively performed using various titrimetric techniques. In general, any titrimetric procedure involves the slow addition of a solution of accurately known concentration (a standard solution) to a solution of unknown concentration (sample to be analyzed) until the reaction between both the solutions is complete. In other words, the standard titrant is added slowly up to the point known as the end point at which the solute analyte in the sample is completely consumed by the solute in the standard solution. Titrimetric methods generally employed in environmental analysis may be broadly classified into the following types: acid-base titration, general redox titration, iodometric titration, argentometric titration, and complexometric titration. The classification highlights the common analytical methods. The chapter highlights some of the aggregate properties and parameters that can be determined by various titrimetric methods.
