The Determination of Formation Constants

An Overview of Computational Methods for Data Processing
  • David J. Leggett
Part of the Modern Inorganic Chemistry book series (MICE)


The interaction of metal ions and ligands, in solution, giving rise to equilibrium mixtures of coordination complexes has been studied systematically since 1941,(1) although many references atest to 30 or more years of earlier research. Until about 1960 data obtained from these studies were subjected to graphical analysis. Many valuable contributions were made by Hazel and Francis Rossotti (their book(2) remains the definitive text on the subject) and by Lars Gunnar Sillen.(3) The impact of Sillen and co-workers on solution equilibria has not been restricted to innovative graphical procedures. In 1961(4) the first general computer program for the evaluation of formation constants from equilibrium data was announced. Many programs have followed from several independent research groups, including the LETAGROP(5) family of computational techniques.
