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.
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.
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.
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.
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.
Dissolved solute (NaCl, salt) will raise the boiling point and lower the freezing point of water. This is known as a colligative property.
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.
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.
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.
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.
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.
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.

The answer is "Freezing point depression" on Apex
If the solute is soluble, it will dissolve in the solvent.
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.
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.
boiling point is increased and freezing point is decreased
