What happens to freezing and boiling points when solute is added?
Wiki User
∙ 9y ago
Adding a solute to a solvent (salt into water for example) disrupts the intermolecular bonds in the otherwise homogeneous fluid. The new solution will have a lower freezing point and higher boiling point as a result. Salt is often added to ice baths to reduce the temperature as well as adding salt to ice to melt it. A solution of 76.7% water and 23.3% salt will freeze at -21.1 degrees Celsius, which is why adding salt to ice will melt it when the temperature is below freezing. The boiling point increases by the same principle of disturbing the homogeneous fluid. Pure unpressurized water can not exist at a temperature greater than 100 C which is why cooks often add a handful of salt to boiling water to enable them to achieve greater cooking temperatures which results in shorter cooking times.

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?
raise its freezing point
What lowers the freezing point and raises the boiling point?
Yes, it is possible if the solution contain solutes.
What is freezing point elevation?
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.
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.
How does the presence of dissolved sodium chloride affect the boiling and freezing point of water?
Dissolved solute (NaCl, salt) will raise the boiling point and lower the freezing point of water. This is known as a colligative property.
Which of these values is most responsible for changing the boiling and freezing points of a solvent?
Boiling point is dependent from pressure. Solutes also have a great impact on the freezing and boiling point.
How does the presence of a solute affect the freezing and boiling points of a solvent?
They usually lower freezing points, think antifreeze. And salt water freezes at a lower temp than fresh, that is why they put salt on ice. And they raise boiling points, think salt in water when making spaghetti. Or, again antifreeze.
Is solute particles change the freezing and boiling points of solutions?
Yesthey do,only if the solution changed and is deferent from the reacting species,
What effects do solutes have on a solvent's freezing and boiling boints?
The effect of a solute on the freezing point and boiling point of a solvent is related to what is known as the colligative property. Upon addition of the solute, the freezing point will be lowered, and the boiling point will be increased. The magnitude of the change will depend on the solute and how many particles it forms upon dissolving, and on the nature of the solvent and the freezing/boiling point constant for that solvent.
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?
raise its freezing point
What lowers the freezing point and raises the boiling point?
Yes, it is possible if the solution contain solutes.
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 adding solute changes the properties of a solvent?
Solutes raise and lower the boiling points of solvents. :)
What is the overall effect adding a solute to a solution?
boiling point is increased and freezing point is decreased
What effect does solute have on the freezing points of the solution?
the temperature at which the solution freezes is lowered.
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.
