Correction of formation constants for ionic strength, from only one or two data points: An examination of the use of the extended Debye-Hückel equation.
The results of an extensive examination show the extended Debye-Hückel equation to be efficacious for the use of as few as one or two formation constant values, for a given metal-complex species, for calculation of the value at a lower ionic strength. Approaches to choosing values for the constants in the extended Debye-Hückel equation are described. A statistical analysis shows the chief source of error in the resulting predicted formation constants to be uncertainties in the literature formation-constant values used as data.
