Stability constants step-wise

MA( , ) + A. MA n-[MA( , )][A] Ky, Kfy being called the step-wise stability constants. Overall stability constants, designated may be evaluated by multiplication of the individual stability constants, e.g. 

The overall stability constants for the following reaction can be calculated from the step-wise constants given above and the selected auxiliary association constant for hydrogen fluoride (log /f" = (3.18 0.02) see Chapter IV)... 

For a step-wise process, consecutive constants are used. In the solvent extraction or extraction by ion exchange resins, the expression for Kj is more complicated than Eq. (25) [211], but is still directly proportional to Pi or Ki. In experiments with single atoms, is defined by the retention time indicated by peaks on elution curves as given by Eq. (1), see Section 1.1. Obtained sequences in the Ki values for a studied series of complexes, e.g. for elements of one group, provide the information about relative stabilities of their complexes, i.e., of Pi.
