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.

∙ 11y agoThe addition of a non-volatile solute decreases the vapor pressure of the solution compared to the pure solvent. The decrease in vapor pressure is related to the mole fraction of the solvent in the solution, as shown by Rauolt's Law. This happens primarily because the solvent molecules are involved in interactions with the solute particles.
The effect on boiling point is pretty simple. The boiling point is the temperature where the vapor pressure of the solution equals atmospheric pressure. If the vapor pressure of the solution is lower than the solvent, then a higher temperature will be required to raise the vapor pressure of the solution to its boiling point.
The effect on solutes on the freezing point of the solution mainly has to do with entropy. The entropy of the solvent in a solution is higher than the entropy of the same pure solvent.

What effects do solutes have on a solvent's freezing and boiling boints?
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.
Which of these values is most responsible for changing the boiling and freezing points of a solvent?
Boiling point is dependent from pressure. Solutes also have a great impact on the freezing and boiling point.
The change in the freezing point of a solvent by the addition of a solute is called?
freezing point depression ..
What will adding solute to pure solvents cause?
Adding a solute to a pure solvent will lower the freezing point, elevate the boiling point, and lower the vapor pressure.
What are the three properties of a solution?
1. Vapor pressure lowering: the decrease in vapor pressure with increasing the number of solute molecules in solution. 2. Boiling point elevation: the increase in boiling point with increasing number of solute molecules in solution. 3. Freezing point depression: the decrease in freezing point with increasing number of solute molecules in solution. 4. Osmotic pressure

How adding solute changes the properties of a solvent?
Solutes raise and lower the boiling points of solvents. :)
How does the presence of a solute affect the freezing and boiling points of a 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.
Why is it when a solute is added to a pure liquid the boiling point increases and the freezing point decreases?
Boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. The vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid. At the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.
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.
Does adding more solute to a solvent raise its freezing point lower its boiling point raise its boiling point or does not affect its boiling point?
raise its freezing point
The change in the freezing point of a solvent by the addition of a solute is called?
freezing point depression ..
What will the nonvolatile solute do to the freezing point of a solvent?
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.
What will adding solute to pure solvents cause?
Adding a solute to a pure solvent will lower the freezing point, elevate the boiling point, and lower the vapor pressure.
What are two ways that solutes affect the properties of solvent?
Solutes lower the freezing point and raise the boiling point of a solvent! :)
