The vapor pressures of aqueous solutions of lithium nitrate at 25° have been measured by the dynamic method for concentrations ranging from 0.1 M up to saturation. From the data obtained has been calculated the activity of the solute and solvent. The activity coefficients of the salt were calculated by means of the "h" function of Lewis and Randall. The free energy of dilution has been calculated. The activity coefficients show a minimum at about 0.6 M. The same thermodynamic properties for aqueous solutions of potassium chloride, potassium iodide and sodium bromide have been recalculated and compared.
