TEMPERATURE-DEPENDENCE OF THE PROPERTIES OF ELECTROLYTE-SOLUTIONS .1. SEMI-PHENOMENOLOGICAL APPROACH TO AN ELECTROLYTE THEORY INCLUDING SHORT-RANGE FORCES

Pair distribution functions f//i//j(r//1,r//2) of a symmetrical ionophoric electrolyte compound Y is identical to C**z// plus A**z// minus in solution are determined with the help of a semi-phenomenological method which avoids a truncated series expansion of the Boltzmann factor of Coulomb ion-ion interaction in the vicinity of the i ion and to introduce the mean potential of short range forces. The appropriate chemical potential of the electrolyte component mu //y( rho ,T) and the relevant transport equations, especially of electrolyte conductance, are given. The concept of ion association is discussed within the framework of this approach.
