Abstract

Vapour pressures of water over saturated solutions of magnesium, calcium, nickel and zinc acetates were determined as a function of temperature. The vapour pressures served to evaluate the water activities, osmotic coefficients and molar enthalpies of vaporization. Molar enthalpies of solution of magnesium acetate tetrahydrate, Δ_solH_m(T = 294.71 K; m = 0.01 mol·kg^-1) = -(15.65 ± 0.97) kJ·mol^-1; calcium acetate, Δ_solH_m(T = 297.18 K; m = 0.01 mol·kg^-1) = -(28.15 ± 0.28) kJ·mol^-1; zinc acetate dihydrate, Δ_solH_m(T = 297.36 K; m = 0.01 mol·kg^-1) = -(22.49 ± 0.90) kJ·mol^-1 and lead acetate trihydrate, Δ_solH_m(T = 297.36 K; m = 0.0086 mol·kg^-1) = (22.46 ± 0.94) kJ·mol^-1, were determined calorimetrically.
