| Abstract: | Enthalpies of solution of NaBr in aqueous ndxtures 0f n-propanol has been measures over various ranges of compositions at 298.15 K, using high-sensitive calorime ter with isothermal shell. On the bases of the results obtained and our former work for the systems NdCl3, BaCl2, NaCl, NaF, and NaI/n-propanol-water, standled enthaJpies ofsolution of afoementioned salts and enthalpies of solvation of soditlm halide in aqueous thextures of n-propanol were calculated. The dependence of enthapies of sulution and solvation of the electrolytes on the nature of ion, composition and structure of the mixed solvents was discussed. |
