Abstract
Saturated vapour pressures of the ternary liquid solutions of urea and ammonium nitrate in water were investigated by the isopiestic method at 15, 25 and 35 °C. The measurements were carried out within the concentrations that are measurable by means of the NaCl standard solutions (i.e. up to the NaCl molality 6 mol/kg). The experimental data are correlated in terms of isotonic solutions of the urea-water and ammonium nitrate-water binary systems.
