Measurement and correlation of osmotic coefficients and evaluation of vapor pressures for solutions of LiN03 and 2-naphthol in ethanol at 298.15K

The osmotic coefficients of solutions of LiN03 and 2-naphthol in ethanol have been measured by the isopiestic method. The experimental osmotic coefficient data were correlated using the Non-Random Two Liquid model (NRTL) and Clegg- Pitzer- Simonson model (C.P.S). The models give reliable results for the correlation of the osmotic coefficient data. The parameters of the considered models obtained by the correlation of osmotic coefficients.
