# What effect does a solute have on the boiling point of a solvent?

## What effect does a solute have on the boiling point of a solvent?

A related property of solutions is that their boiling points are higher than the boiling point of the pure solvent. Because the presence of solute particles decreases the vapor pressure of the liquid solvent, a higher temperature is needed to reach the boiling point.

### What effects do solutes have on a solvents freezing and boiling points quizlet?

What effects do solutes have on a solvent’s freezing and boiling points? Solutes lower the freezing point and raise the boiling point of a solvent.

#### What effect does a solute have on the freezing and boiling points of the solution?

The effect of adding a solute to a solvent has the opposite effect on the freezing point of a solution as it does on the boiling point. A solution will have a lower freezing point than a pure solvent.

How does the solute affect the freezing point of a solvent?

The presence of a solute lowers the freezing point of any solvent; this effect is called freezing-point depression. The introduction of a solute reduces the activity of the liquid phase solvent, thereby reducing the rate of freezing.

What are the normal boiling points of the solvent and the solution?

Normal boiling point = 100.0oC. 1.0 M NaCl solution – microscopic view. Normal boiling point = 101.0oC….

solvent normal boiling point, oC Kb, oC m-1
chloroform 61.3 3.63
nitrobenzene 210.9 5.24

## How do you know which solution has the highest boiling point?

That is they depend upon the concentration of solute particles present. Pure water has a normal boiling point of 100C, and by adding a solute the boiling point is raised. The more solute particles, the higher the boiling point.

### How does the addition of salt affect the freezing and boiling points of water?

The more salt (or any solute) added to water, the more you raise the boiling point. Freezing point depression is another colligative property that works the same way: If you add salt to water, you lower its freezing point as well as raise its boiling point.

#### How does the addition of salt affect the freezing and boiling points of water quizlet?

The addition of salt lowers the melting point of water, which makes the ice cube easier to melt. Because colligative properties depend on the concentration of particles, freezing point depression of water will be further reduced.

Why freezing point of a solvent decreases when a solute is added?

Freezing point depression is the phenomena that describes why adding a solute to a solvent results in the lowering of the freezing point of the solvent. Adding solute to a solvent will essentially dilute the solvent molecules, and according to Raoult’s law, this leads to a decrease in vapor pressure.

Is antifreeze a solute?

Antifreeze = Solute – ethylene glycol, Solvent – water Lemonade = Solutes – lemon juice and sugar, Solvent – water Soda Pop = Solute – syrup and CO2 gas, Solvent – water Air = Solutes – oxygen and other gases, Solvent – nitrogen Gold jewelry = Solute – copper, Solvent – gold Sterling Silver = Solute – copper, Solvent – …

## What is molal freezing point depression constant of a solvent?

freezing point depression: The difference in temperature between the freezing point of the pure solvent and that of the solution. molal freezing-point depression constant: A constant that is equal to the change in the freezing point for a 1-molal solution of a nonvolatile molecular solute.

### What factors affect freezing point?

Factors That Affect the Freezing Point

• Types of molecules: The types of molecules that constitute a liquid affect its freezing point.
• On the other hand, if the intermolecular forces of attraction between molecules of the liquid are weak, then the freezing point becomes low.
