WebDepression in Freezing Point: Freezing point depression happens when the freezing point of a liquid is lowered by the addition of a different compound to it. The solution contains a lower freezing point than that of pour solvent. It is a colligative property of a dilute solution that contains a non-volatile solute. Answer and Explanation: 1 WebMay 1, 2012 · The approach to developing lower freezing point molten salt mixtures involves systematic investigation of molten salt properties and prediction of new eutectic salt mixtures. Literature review of salt phase diagrams shows that the LiNO 3 –KNO 3 –NH 4 NO 3 ternary system possesses a eutectic mixture with freezing point less than 100 °C.
