Consider the following statements regarding colligative properties:

(A) Colligative properties depend on the nature of the solute.

(B) Colligative properties depend on the number of solute particles.

(C) Osmotic pressure is one of the colligative properties.

(D) Elevation in boiling point and depression in freezing point are examples of colligative properties.

Consider the following statements regarding Raoult’s law:

(A) Raoult’s law holds true only for ideal solutions. 

(B) Raoult’s law states that the vapor pressure of a solvent in a solution is proportional to the mole fraction of the solvent.

(C) Raoult’s law is not valid for solutions with highly volatile solutes.

(D) Raoult's law applies to both ideal and non-ideal solutions.

Consider the following statements regarding solutions:

(A) Solutions with the same boiling point and freezing point are said to be ideal solutions.

(B) Colligative properties depend on the number of solute particles.

(C) In ideal solutions, intermolecular forces between solvent and solute are the same.

(D) Osmosis is the movement of solvent from lower concentration to higher concentration of solute.

Consider the following statements regarding the molal freezing point depression constant:

(A) It depends on the solvent used.

(B) It is the same for all solvents.

(C) The value of the molal freezing point depression constant is used to calculate the depression in freezing point.

(D) Molal freezing point depression constant is dependent of the amount of solute.
