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.
What else can I help you with?
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 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.

When a solute is dissolved in a solvent, it typically raises the boiling point of the solvent, a phenomenon known as boiling point elevation. The presence of the solute disrupts the solvent's structure, requiring more energy (heat) to reach the boiling point. Conversely, the solute usually lowers the freezing point of the solvent, a process known as freezing point depression. The effect of the solvent on the conductivity of the solute can vary depending on the nature of both the solute and solvent.
Describe how properties change after a solvent dissolves a solute?
When a solute dissolves in a solvent, the physical and chemical properties of the solution can change significantly. For instance, the boiling and freezing points of the solvent may be altered, a phenomenon known as boiling point elevation and freezing point depression. Additionally, the solution's conductivity can increase if the solute dissociates into ions, such as in the case of salt in water. Overall, the resulting solution exhibits properties distinct from those of the individual components.
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.
Which of these values is most responsible for changing the boiling and freezing points of a solvent?
The concentration of solute in the solvent is most responsible for changing the boiling and freezing points. When a solute is added to a solvent, it disrupts the normal intermolecular forces between solvent molecules, which results in a change in the boiling and freezing points of the solvent.
Is solute particles change the freezing and boiling points of solutions?
Yes, solute particles change the freezing and boiling points of solutions. This is known as colligative properties, where the presence of the solute affects the physical properties of the solvent. The freezing point decreases and the boiling point increases compared to the pure solvent.
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.
What is the relationship between boiling point elevation and freezing point depression in a solution?
Boiling point elevation and freezing point depression are both colligative properties of a solution. Boiling point elevation occurs when the boiling point of a solvent increases when a solute is added, while freezing point depression happens when the freezing point of a solvent decreases with the addition of a solute. These phenomena are related because they both depend on the concentration of solute particles in the solution, with boiling point elevation and freezing point depression being proportional to the number of solute particles present.
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 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.

What is the tendency of a solute to change the melting point of a solid called?
The answer is "Freezing point depression" on Apex
What happens to a solution when solute is added?
If the solute is soluble, it will dissolve in the solvent.
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.
How does the phenomenon of freezing point depression and boiling point elevation affect the properties of a solution?
Freezing point depression and boiling point elevation are both colligative properties that occur when solute particles are added to a solvent. Freezing point depression lowers the temperature at which a solution freezes, while boiling point elevation raises the temperature at which a solution boils. These changes in the freezing and boiling points affect the physical properties of the solution, making it different from the pure solvent.
