This is not a common phenomenon. Usually it is boiling points that are elevated, and freezing points are depressed. It is possible that a freezing point could be raised (elevated) due to the presence of an impurity with a much higher freezing point.
Changes in boiling and freezing points are typically due to impurities in compound.
See the Related Questions to the left for more information about freezing point depression and boiling point elevation problems.
Freezing point elevation is the phenomenon where the freezing point of a solvent is lowered when a solute is added to it. This occurs because the presence of solute particles disrupts the formation of solvent crystals, requiring a lower temperature to freeze. It is a colligative property that depends on the number of solute particles rather than their identity.
Boiling-point elevationdescribes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling pointthan a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water.

How does elevation effect freeze point?
As elevation increases, the atmospheric pressure decreases. This causes the boiling point of water to decrease, but the freezing point remains relatively unaffected. Therefore, elevation does not significantly impact the freezing point of water.
List four properties of a solution that depend on the total concentration but not the type of particle or particles present as solute?
Osmotic pressure Boiling point elevation Freezing point depression Vapor pressure lowering
Does adding more solute to a solvent raise its freezing point lower its boiling point raise its boiling point or does not affect its boiling point?
Adding more solute to a solvent raises its boiling point and lowers its freezing point. This is known as boiling point elevation and freezing point depression. The presence of solute particles disrupts the organization of solvent molecules, making it more difficult for them to change phase.
What lowers the freezing point and raises the boiling point?
Adding solutes, such as salt or sugar, to a solvent can lower the freezing point and raise the boiling point. This phenomenon is known as freezing point depression and boiling point elevation, respectively. The presence of solutes disrupts the normal crystal structure in the solvent, requiring lower temperatures to freeze and higher temperatures to boil.
The physical properties of a solution that differ from those of its solute and solvent include freezing point boiling point and what?
The physical properties of a solution that differ from those of its solute and solvent include boiling point elevation, freezing point depression, osmotic pressure, and vapor pressure changes.
How does elevation effect freeze point?
As elevation increases, the atmospheric pressure decreases. This causes the boiling point of water to decrease, but the freezing point remains relatively unaffected. Therefore, elevation does not significantly impact the freezing point of water.
What are examples of freezing point depression boiling point elevation and vapor point lowering?
The freezing is ag gago weak
How are freezing point depression and boiling point elevation useful?
the main applicative use of freezing point depression and boiling point elevation is to calculate the molecular mass of a non volatile solute in a pure solvent.
How does elevation in temperature affect the freezing point of water?
It doesn't.
What is the boiling and freezing point when it is 1.92 mole of naphthalene C10H8 in 16.8 mole of chloroform?
The boiling point elevation and freezing point depression of a solution are colligative properties that depend on the molality of the solute particles. Given the information provided, you would need the constants for the boiling point elevation and freezing point depression of the solvent (chloroform) to calculate the new boiling and freezing points.
List four properties of a solution that depend on the total concentration but not the type of particle or particles present as solute?
Osmotic pressure Boiling point elevation Freezing point depression Vapor pressure lowering
What is the tendency of a solute to change the melting point of a solid called?
The answer is "Freezing point depression" on Apex
Does freezing temperature change at higher altitudes?
Yes, the freezing temperature decreases as altitude increases. This is because the air becomes thinner at higher altitudes, leading to lower air pressure. As a result, the boiling point of water decreases and so does its freezing point.
Compared to the pure water an aqueous solution of calcium chloride has a?
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.
Does adding more solute to a solvent raise its freezing point lower its boiling point raise its boiling point or does not affect its boiling point?
Adding more solute to a solvent raises its boiling point and lowers its freezing point. This is known as boiling point elevation and freezing point depression. The presence of solute particles disrupts the organization of solvent molecules, making it more difficult for them to change phase.
