Complexometric Titration and its Application to Silicate Analysis

Chemical analysis for knowing the quantitative compo-sition of a substance is considered important and essent-ial for evaluation and characterization of silicate raw materials and finished products. However, the classic-al 'wet' chemical methods involving lengthy and time consuming steps of successive separations of groups by precipitation and reprecipitation can not serve the purpose of quality control since the effectiveness of quality control is largely determined by the speed with which the determination of critical parameters, composit-ions and properties involving evaluation of raw materials and finished products are made. Attempts have therefore, been constantly made for development of rapid and accurate methods of chemical analysis. The literature on silicate analysis reveals spectacular advancement both in wet
chemical and instrumental methods of analysis after the last World War II. In wet chemical analysis complexometric
titration with EDTA (Ethylene Diamine Tetra Acetic Acid),
a versatile complexing agent first introduced by Schwar-zewbach is probably the best contribution till now in 20th century.
