Investigation of Vapor Pressure of Binary Solutions of ZnCl₂ + C₂H₅OH at T = (298.15 to 323.15) K using a Static Method

Vapor pressures p of ZnCl₂ + C₂H₅OH at T = (298.15 to 323.15) K were measured, osmotic φ and activity γ coefficients; and activity of solvent a_s have been evaluated. The experiments were carried out in the molality range m = (0.32345 to 5.13771) mol kg⁻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.
