%X The aim of this work is to calculate ion-ion interaction, density of organic-aqueous mixtures of Acetonitrile-water (AN-H 2O), density of saturated solutions of BDPA, salvation volumes (Van der Waals volume V M, molar volume V M and electrostriction volume V e) and solvated radii (r o) from solubility experiments. It was found that values of the log activity coefficient ( ¦Ã+ ) of BDPA in (AN-H2O) mixture were decreases by increasing in the content of the organic solvent used. The values of the log ¦Ã+ found to decrease with the increase in temperature. The densities and the molar volumes of the saturated solutions of BDPA decrease by increasing ratio of AN and also increases by increasing in temperature. All the electrostriction volumes calculated for BDPA having negative values. The electrostriction volumes increase in negativity on increasing the percentages of the organic solvent. The solvated radii of BDPA are increased as the organic solvent content increase and as the temperature increase.
