ABSTRACT
Vapor pressures p of CaCl2 + CH3OH and CaCl2 + C2H5OH at T ) (298.15 to 323.15) K were measured, osmotic (?) and activity (c) coefficients and activity of solvent (as) have been evaluated. The experiments were carried out for CaCl2 + CH3OH solutions in a molality range m ) (0.10402 to 2.59613) molakg-1 and for CaCl2 + C2H5OH solutions in a molality range m ) (0.12359 to 2.12091) molakg-1. The Antoine equation for the empirical description of the experimental vapor pressure results and the Pitzer-Mayorga model with inclusion of ionic strength dependence of the third virial coefficient for the description of calculated osmotic coefficients were used. The parameters of Pitzer-Mayorga model were used for evaluation of activity coefficients.
