Mixed solvent effect on the ion association process

The ion association process (or opposite to it - ion dissociation process) has been studied in detail in comparison with other types of chemical equilibrium in solutions. The modem 

State of the theory of individual solvent effects on equilibrium constant of ion association process (Kj) is described in monographs by Izmailov and Barthel.  

The formation of free (preferably solvated) ions is due to a successive equilibrium states proceeding in solution  

The true constant of ion association is a ratio of ionic associate concentration Cat p An to ion concentration product. If ionic associate concentration is xmknown (as is true in many cases), ion association constant is calculated from the analytical concentration of dissolved substance  

The general theory of ionic equilibrium leads to the conclusion that ion association constant in universal or conditionally universal media, in accordance to the equation [9.53a], depends exponentially on reciprocal value of permittivity
