The optimum mole ratio of lithium salts in the H{sub 2}O + LiBr + LiNO{sub 3} + LiI + LiCl system was experimentally determined to be LiBr:LiNO{sub 3} LiI:LiCl = 5:1:1:2. The solubilities were measured at temperatures from 252.02 to 336.75 K. Regression equations on the solubility data were obtained with a least-squares method. Average absolute deviations of the calculated values from the experimental data were 0.15% at temperatures <285.18 K and 0.05% at temperatures {ge}185.18 K. The vapor pressures were measured at concentrations ranging from 50.0 to 70.0 mass % and at temperatures from 330.13 to 434.88 K. The experimental data were correlated with an Antoine-type equation, and the average absolute deviation of the calculated values from the experimental data 65.0 mass % and temperatures from 298.15 to 328.15 K. The average absolute deviation of the values calculated by the regression equation from the experimental data was 0.24%.
