This book describes potentiometric methods for determining stability constants and explains how these constants can be used to describe metal ion speciation in complex environmental and biological systems. It also provides three original computer programs on disk for calculating stability constants and for using them to determine concentrations of molecular species in solution. Numerous sample calculations show how to avoid common errors. The authors give examples of calculations for simple metal chelates, for metal complexes of large organic molecules, and for mixtures containing several metal ions and complexing agents in aqueous solution. They also describe common errors in calculating stability constants and how to avoid them.
Part 1 Introduction: stability constants - early work; recent developments; historical evolution of computational methods; purpose of this book. Part 2 Equilibrium constants, protonation constants, formation constants: concentration constants and activity constants; conventions employment for expressing equilibrium constants; equilibrium constants and stability constants for EDTA; species distribution curves. Part 3 Experimental methods for measuring equilibrium constants: methods available; potentiometric pH measurements; displacement methods; pH and p[H]measurement of metal complex equilibria: materials, the reaction mixture; calibration of the potentiometric apparatus; the experimental runs; computation of stability constants.Part 4 Common errors and their elimination or minimization: measurements errors; calibration and electrode care; reagents; equilibrium measurements; calculations; selection of the model. Part 5 Examples of stability constant determination: iminodiacetic acid (IDA); procedure for IDA; C-BISTREN; procedure for C-BISTREN. Part 6 Macroscopic and microscopic constants: some definitions and concepts; ionization of tyrosine; microscopic protonation equilibria of DOPA; general comments and conclusions. Determination of stability constants and species concentrations of complex systems: a mixed-ligand binuclear dioxygen system; non-aqueous solvents; complex multicomponent systems; equilibrium with solid phases; equilibrium involving hydrolytic species; species distributions of hydroxo and fluoro complexes of AI(III). Part 7 Critical stability constants and their selection: general criteria; examples of critical data selection; need for additional critical constants. Part 8 Development of a complete metal complex data base: introduction; linear stability. constant correlations; estimation of estability constants not measured experimentally; metal speciation in sea water with and without added ligands.
