Freezing point purified water

WebFeb 27, 2024 · The freezing points away solutions are all lower than such concerning the pure solvent. The freezing point depression is directly proportional to one molality is the solute. The thawing points of solutions are all lower then that of the purified solvent. The thawing point signs are directly proportionally in the molality to and solute. WebRaising pressure actually lowers water’s freezing point a little. That’s because ice occupies more volume than liquid water, so squeezing tends to drive it to become liquid. That’s rather unusual for freezing points, since the solid occupies less space than the liquid for most substances. Mike W. (published on 10/22/2007)
