Salt lowers the freezing point of water. So will sugar. If one tablespoon of solid (salt or sugar) is dissolved in ¼ cup of water, which material, salt or sugar will lower the freezing point of the water by the greater amount? Why?© BrainMass Inc. brainmass.com March 4, 2021, 9:08 pm ad1c9bdddf
Depression in freezing point can be given as:
ΔTf = Kf x mB
ΔTf, the freezing point depression
Kf, the cryoscopic constant, which is dependent on the properties of the solvent.
