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?
The concentration of solute in the solvent is most responsible for changing the boiling and freezing points. When a solute is added to a solvent, it disrupts the normal intermolecular forces between solvent molecules, which results in a change in the boiling and freezing points of the solvent.
What will adding solute to pure solvents cause?
Adding solute to pure solvents will cause the solute to dissolve in the solvent, forming a solution. This process can alter the properties of the solvent, such as its boiling point, freezing point, and osmotic pressure, depending on the amount and nature of the solute added.
What is the relationship between boiling point elevation and freezing point depression in a solution?
Boiling point elevation and freezing point depression are both colligative properties of a solution. Boiling point elevation occurs when the boiling point of a solvent increases when a solute is added, while freezing point depression happens when the freezing point of a solvent decreases with the addition of a solute. These phenomena are related because they both depend on the concentration of solute particles in the solution, with boiling point elevation and freezing point depression being proportional to the number of solute particles present.
The change in the freezing point of a solvent by the addition of a solute is called?
The change in the freezing point of a solvent by the addition of a solute is called freezing point depression. This phenomenon occurs because the presence of the solute disrupts the crystal lattice formation of the solvent, requiring a lower temperature for freezing to occur.

The physical properties of a solution that differ from those of its solute and solvent include freezing point boiling point and what?
The physical properties of a solution that differ from those of its solute and solvent include boiling point elevation, freezing point depression, osmotic pressure, and vapor pressure changes.
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.
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?
Adding more solute to a solvent raises its boiling point and lowers its freezing point. This is known as boiling point elevation and freezing point depression. The presence of solute particles disrupts the organization of solvent molecules, making it more difficult for them to change phase.
How adding solute changes the properties of a solvent?
Adding a solute to a solvent can change its properties by altering the boiling point, melting point, viscosity, and osmotic pressure. The presence of solute particles disrupts the solvent's ability to vaporize or freeze, leading to changes in these properties. The more solute added, the greater the impact on the solvent's properties.

Explain why the vapor pressure boiling point and freezing point of an aqueous solution if a nonvolatile solute are not the same as those of the pure solvent?
The presence of a nonvolatile solute in an aqueous solution lowers the vapor pressure of the solution, raising its boiling point and lowering its freezing point compared to the pure solvent. This occurs due to the solute molecules occupying space at the surface of the solution, reducing the number of solvent molecules escaping into the vapor phase. As a result, a higher temperature is needed to reach the same vapor pressure as the pure solvent for boiling, and a lower temperature is needed for the solution to freeze.
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.
