Vapor pressures p of ZnBr2 + CH3OH and ZnCl2 + CH3OH solutions at T = (298.15 to 323.15) K were measured, activity of solvent as and osmotic ϕ coefficients have been evaluated. The experiments were carried out for the ZnBr2 + CH3OH solutions in the molality range m = (0.19972 to 11.05142) mol · kg−1 and for the ZnCl2 + CH3OH solutions in the molality range m = (0.42094 to 8.25534) 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.
