Studies on Coördination Compounds. I. A Method for Determining Thermodynamic Equilibrium Constants in Mixed Solvents^{1, 2}

Abstract

In the past "pH" titrations in partially non-aqueous solvents have been made in order to determine the stability of coordination compounds. The interpretation of such data has been reconsidered with the object of obtaining thermodynamic stability constants. It is assumed that the activity coefficient of electrolytic solutes in these solvents is determined solely by the solvent composition and the ionic concentration. Finally, experimental substantiation of the assumption is given and the method of calculating thermodynamic stability constants is discussed.
