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.

∙ 9y agoBoiling-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.

∙ 8y agoThe formula is:
ΔTb = Kb · bsolute · i
where:
- Kb is the ebulioscopic constant of the solvent
- bsolute is the molality of the solvent
- i is the van't Hoff factor and depends on the number of ions formed in solution

What lowers the freezing point and raises the boiling point?
Yes, it is possible if the solution contain solutes.
What will the nonvolatile solute do to the freezing point of a solvent?
This is the property of freezing point depression and boiling point elevation. This is because of the solute absorbing the energy added to the system to heat its own molecules and so it would require more energy to boil the solvent. Likewise for freezing point depression, the molecules retain more energy.
Method of measuring the boiling point elevation by beekmanns method?
Ernst Otto Beckmann is not known for having his own method for measuring the boiling point elevation. Beckmann used ebullioscopy, which is the method for measuring the boiling point elevation, and cryoscopy, which is the method for measuring freezing point depression, to determine molecular masses of objects. He invented a thermometer to differentiate between temperature differences and values. This thermometer is known as the Beckmann Thermometer.
How does salt raises the melting point of water?
It doesn't increase the melting point of ice, instead, it lowers it. When a solute (which is the salt) is added to a solvent (which is what dissolves it), the boiling point is increased while both the freezing and melting points are decreased. This is evident in the boiling point elevation and the freezing/melting point depression system.
List four properties of a solution that depend on the total concentration but not the type of particle or particles present as solute?

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.
Does freezing temperature change at higher altitudes?
Elevation has minimal affects on the freezing point of water as it doesn't deal with gas molecules as boiling does. Elevation affects the boiling point of water because the air pressure changes with elevation.
What is the tendency of a solute to change the melting point of a solid called?
The answer is "Freezing point depression" on Apex
How do the melting and boiling points of water differ from those of a sugar water solution?
The phenomenon of boiling point elevation is analogous to freezing point depression
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.
What lowers the freezing point and raises the boiling point?
Yes, it is possible if the solution contain solutes.
