This volume is concerned with methods that are available for the calculation of for- mation constants, in particular computational procedures. Although graphical meth- ods have considerable value in the exploration of primary (raw) data they have been overtaken by computational methods, which, for the most part, take primary data and return the refined formation constants. Graphical methods are now considered com- plementary to these general computational procedures. This volume brings together programs that span the lifetime of computer-assisted determination of formation constants. On one...
