Question

question 8 (1 point)
what happens to each of the four when a solute is added; increase, decrease, or no change ?
vapor pressure 1
boiling point 2
freezing point 3
osmotic pressure 4
u. increase v. decrease w. dialysis x. osmosis
y. shrinkage z. swelling aa. no change

Explanation:

• Vapor pressure: When a solute is added, the vapor pressure of the solution decreases. This is because the solute particles occupy some of the surface area, reducing the number of solvent molecules that can escape into the vapor phase.
• Boiling point: The boiling point of a solution increases when a solute is added. A higher temperature is required to reach the boiling point because the vapor pressure of the solution is lower than that of the pure solvent.
• Freezing point: The freezing point of a solution decreases when a solute is added. The presence of solute particles disrupts the formation of the solid lattice structure of the solvent.
• Osmotic pressure: The osmotic pressure of a solution increases when a solute is added. Osmotic pressure is a colligative property that depends on the concentration of solute particles.

Answer:

1. V. decrease
2. U. increase
3. V. decrease
4. U. increase
