Question

The colligative property of a solution is A. vapour pressure
B. osmotic pressure
C. boiling point
D. freezing point
-----Thanks-----​

Answer 1

Answer:

A. Vapour pressure

Explanation:

Colligative Properties. Colligative properties of solutions are properties that depend upon the concentration of solute molecules or ions, but not upon the identity of the solute. Colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.

Answer 2

Colligative properties are those properties that are dependent on the ratio of the number of solutes to the number of solvents.

Explanation:

Osmotic pressure , lowering of vapour pressure,elevation of boiling point are the colligative propeties of the solution.

• In this question the answer is Osmotic pressure is the correct answer
• Osmotic pressure is the minimum pressure that must be applied to the solution to prevent the inward flow of solution.
