The Mc activity coefficient function for acid–base equilibria. Part 5. The Mc activity coefficient for a reliable estimate of thermodynamic values
Abstract
The general validity of the relationship log (fZifAi/fDi)=nij(log fZjfAj/fDj)(Z = base, A = acid, D = conjugated acid) has been tested using different weak bases involved in protonation, ionization, and rate processes. Experimental data in aqueous sulphuric and perchloric acid have been treated simultaneously by a mathematical procedure which allows the transference of data from one acid to another. The analysis of the thermodynamic values of equilibria and rate processes shows the advantages both of the new treatment and of the latter estimated Mcf(x) functions.
