Diffusion coefficients and complex equilibria in solution-I theory: Diffusion coefficients of complex species.
It is shown that in principle it is possible to obtain values of the formation constants of metal complexes in solution from values of diffusion coefficients. It is also confirmed that, in a system of successively formed complexes, there is a linear relationship between the square root of the diffusion coefficients and the co-ordination numbers of the complexes formed. In some instances such analysis has shown that revision of some previously reported formation constant data is required.
