The freezing point of an aqueous solution is the temperature at which the solution changes from a liquid to a solid state. This temperature is dependent on the concentration and type of solute dissolved in the water.
Adding a solute to water lowers its freezing point. This is due to the fact that the solute particles disrupt the formation of ice crystals, making it more difficult for water molecules to arrange themselves into a solid structure.
The freezing point depression equation is ΔT = Kf * i * m, where ΔT is the change in freezing point, Kf is the molal freezing point depression constant, i is the van't Hoff factor (related to the number of particles in the solution), and m is the molality of the solution.
Salt has a greater effect on the freezing point of water because it dissociates into two ions (sodium and chloride) when dissolved in water, whereas sugar does not dissociate. This results in a greater disruption of the water molecules and a lower freezing point.
No, the freezing point of an aqueous solution can never be higher than that of pure water. This is because the solute particles always lower the freezing point, even if the solute is a substance that raises the boiling point of water.
