Which of the following liquids will have the lowest freezing point?
According to colligative properties of solutes, depression of freezing point follows the number of particles produced upon solubilization. It depends on the concentration of #CdI_2 #, which is 0.39 molal.
Theoretically #CdI_2# giving three ions per formula when dissolved in water, should give the second highest freezing depression, at that concentration.
On the other hand #LiF# is actually sparingly soluble in water (about 0.071 M), and cannot be dissolved at 0.65 molal.
So the answer depends on whether we want to represent physical reality or answer a theoretical question. [Sucrose and glucose give only one particle per molecule.]

The molal freezing-point-depression constant of water is 19. A 2.05 m aqueous solution of some unknown had a boiling point of 102.1 °C. Which one of the following could be the unknown compound?
Which of the following 0.10 M aqueous solution will have the low – freezing point of water gets lowered by 1.86 degrees cellsius for each mole of solute particles in solution. At what temperature LPG Gas Freeze?For liquid to reach the freezing point first, the liquid with higher molecular mass or stronger intermolecular force would have higher freezing point Freezing point is the temperature at which a substance turns from liquid to solid; the lowest freezing point is that of helium, and is at only a…ions in solution which of the following has the lowest freezing point? II and III one of the following statements most accurately relates the properties of a liquid at room temperature with its vapor.
Which of the following liquids will have the lowest freezing point… – You can lower the freezing point of some liquids by mixing a second, soluble substance into them; this is how road salt keeps melt-water from refreezing in cold temperatures. By mixing one liquid with another compatible substance, you lower the freezing point of the liquid.Colligative properties: Freezing point depression. The depression in freezing point will depend on the total number of particles present, and the molality of those particles. We are given the molarity (not molality) of the different solutions so we'd really need the density of these solutions to compute molality.This is a step by step verification of the answer by our certified expert. What is the magnitude of the a) electric force, and b) gravitational force exerted by one proton on the other proton if the two particles are 3.80 x 10-10 m apart?
