solute is which we are mixing and solvent is that in which we are mixing solute

The similarities between the solute and solvent can lead to stronger interactions between them, increasing the boiling point of the solution due to enhanced solute-solvent cohesion. Conversely, dissimilarities may reduce these interactions, lowering the boiling point by weakening the solute-solvent bonds. Overall, the impact on boiling point depends on the specific chemical characteristics of the solute and solvent involved.

Explain why a solution has a lower boiling point than the pure solvent?
When a solute is added to a solvent, the vapor pressure of the solution decreases compared to the pure solvent. This means the solution needs less energy to overcome atmospheric pressure and boil. As a result, the boiling point of the solution is lower than that of the pure solvent.
Why would the boiling point of a solution be higher than that of a pure solvent?
The boiling point of a solution is higher than that of a pure solvent because the presence of solute particles disrupts the solvent's ability to form vapor, requiring more energy to reach the boiling point. This phenomenon, known as boiling point elevation, is a colligative property dependent on the number of solute particles in the solution.
What happens to a solution when solute is added?
If the solute is soluble, it will dissolve in the solvent.
What effect does adding a solute have on the boiling of solution?
The solution freezes at a lower temperature and boils at a higher temperature.
When table salt and sugar are dissolved in water it is observed that the boiling point of 0.10 m Na-Cl is higher than that of 0.10 m?
This phenomenon is known as boiling-point elevation, where the boiling point of a solution is higher than that of the pure solvent. This occurs because the presence of solute particles (such as Na-Cl or sugar) in the solvent disrupts the solvent-solvent interactions, making it harder for the solvent molecules to escape into the vapor phase. As a result, more heat is required to raise the solution to its boiling point compared to the pure solvent.

The boiling point of a liquid solution is?
Higher then the boiling point of the solvent.
What is boiling out a solvent?
Boiling out a solvent is when you heat up a solution to a high enough temperature that the solvent (liquid) evaporates, leaving behind whatever you have dissolved.
What happens to a solvent when a nonvolatile solute is added to it?
It increases the boiling point of the solution and it increases the temperature range over which the solution remains a liquid.
How do you obtain a pure solvent from a solution by distillation?
To obtain a pure solvent from a solution by distillation, heat the solution in a distillation apparatus. The solvent will evaporate first due to its lower boiling point, leaving behind the solute. The vapor is then condensed back into liquid form, resulting in a pure solvent separate from the solute.
How do different solutes affect boiling point?
Adding solutes to a solvent raises its boiling point by increasing the boiling point elevation. This is due to the solute particles disrupting the solvent's ability to vaporize. The extent of boiling point elevation depends on the number of solute particles present in the solution and not the identity of the solute itself.
What happens to the boiling point of a solution as the concentraion increases?
Boiling-point elevation describes 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 point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope.

What is the boiling point of a 2.86 m solution of ammonium nitrate NH4NO3 Assume that the solvent is water which has a Kb of 0.51ºC m and a boiling point of 100.0ºC?
To find the boiling point elevation of the solution, you can use the formula: ΔTb = i * Kb * m, where i is the van't Hoff factor, Kb is the ebullioscopic constant, and m is the molality of the solution. Plug in the values given and solve for ΔTb. Then, add this value to the boiling point of the solvent (100.0°C) to find the boiling point of the solution.
