Abstract

Vapour pressures of saturated aqueous solutions of BaCl2, Mg(NO3)2, Ca(NO3)2, K2CO3, and ZnSO4 were measured in the 283 K to 313 K temperature range using evaporimetric technique and compared with the literature values. From the vapour pressures, the water activities, osmotic coefficients, and molar enthalpies of vaporization and solution at saturation were evaluated.
