Abstract

The aquation kinetics of pentaamine-(p-toluenesulfonamido)cobalt(III) ion were studied in the presence of NaCl, NaBr and NaClO₄ as supporting electrolytes as well as in binary aqueous-organic mixtures with methanol, isopropyl alcohol, tert-butylalcohol, dioxane and acetonitrile as non aqueous cosolvents. It was found that the association between the complex ion and Cl^-, Br^- and ClO₄^- ion takes place and the association constants were evaluated from kinetic measurements. Some conclusions concerning the effect of non aqueous component of the solvent on solvation of the initial and transition state have been drawn from the experimental data obtained.
