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.
How can one determine the boiling point of a solution?
The boiling point of a solution can be determined by measuring the temperature at which the solution changes from a liquid to a gas. This temperature is typically higher than the boiling point of the pure solvent due to the presence 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.
Why would the boiling point of a solution be higher than that of a pure solvent?
Liquids in a pure state have a specific boiling point.Water, for example, boils at 100 oC at 1 atm. However once there are impurities in the liquid the boiling point will be elevated. The degree of elevation depends on the quantity of impurity in the liquid.
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.

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?
When a solute is added to a solvent, the boiling point is raised according to the equation ΔTb=Kbm. Thus, the boiling temperature of a solution can be described by: Tb(solution)=ΔTb + Tb(pure solvent). However, for the purposes of this question, adding a solute increases the boiling point of a solution.
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 role does the solvent play in a solution?
The solvent in a solution is the substance that dissolves other substances, known as solutes. It plays a crucial role in dissolving the solutes and creating a homogeneous mixture. The solvent determines the physical properties of the solution, such as its density, viscosity, and boiling point.
