چکیده مقاله :
The ion-pair association constant values, related to the reaction + were determined by means of the NMR spectroscopy. The values of the thermodynamic functions of the ion pairing process were calculated on the basis of the NMR results. In addition, the association entropy was found to be dependent on the temperature. Comparing the experimental data and the Fuoss theory it is found that ion-pair is formed in the aqueous solution.
