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.
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.
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.
How does the addition of solute affect freezing and boiling point and vapor pressure on a solvent?
A non-volatile solute affects increases osmotic pressure. This is a colligative property. There will be a higher osmotic pressure required to prevent the solvent from flowing into the solution because the solvent has a higher chemical potential without solute in it.
The boiling point of a liquid solution is?
Higher then the boiling point of the solvent.

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.

Compared to the pure water an aqueous solution of calcium chloride has a?
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.
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.
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.

Why does adding a solute to a solvent raise the boiling point of the solution?
A nonvolatile ( not readily evaporated) solute elevates the boiling point of a solvent (the temperature at which the solvent boils) because its presence lowers the vapor pressure of the solvent. * The normal boiling point of a liquid occurs at the temperature where the vapor pressure is equal to 1 atmosphere. * The presence of a nonvolatile solute decreases the number of solvent molecules per unit volume , so less molecules escape form the liquid. Thus the vapor pressure of the solvent decreases. * Therefore, such a solution with lower vapor pressure must be heated to a higher temperature than the boiling point of the pure solvent to reach a vapor pressure of 1 atmosphere.
Which is a better solvent for boiling point elevation ethanol or water?
Ethanol is a better solvent for boiling point elevation compared to water. This is because ethanol has a higher boiling point than water. When a solute is added to ethanol, it will raise the boiling point of the solution more significantly than if the same solute were added to water.
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.
