**Question 4**: Consider a liquid with a boiling point of 230°C, a freezing point of 24°C, and a vapor pressure of 0.01 atm. What will happen to each of these properties if a soluble salt is added to the liquid? a. Boiling Point b. Freezing Point c. Vapor Pressure --- *Explanation*: - **Boiling Point**: Adding a soluble salt to the liquid will typically increase the boiling point due to boiling point elevation. This occurs because the presence of solute particles reduces the vapor pressure of the liquid, requiring a higher temperature to reach the atmospheric pressure. - **Freezing Point**: The addition of a soluble salt will lower the freezing point of the liquid. This colligative property, known as freezing point depression, happens because solute molecules disrupt the formation of the solid lattice structure necessary for the liquid to freeze. - **Vapor Pressure**: The vapor pressure of the liquid will decrease when a soluble salt is added. This occurs because the solute particles occupy space at the surface of the liquid, reducing the number of solvent molecules that can escape into the vapor phase. These changes are examples of colligative properties, which depend on the number of solute particles in a solution rather than the identity of the solute.
