Which of the following is NOT a colligative property of solutions?

a) Freezing point depression
b) Boiling point elevation
c) Lowering of vapor pressure
d) Temperature

Respuesta :

Answer:

The correct answer is d)temperature. See the answer below, please.

Explanation:

Colligative properties are those physical properties that depend on the number of molecules present in a solution, regardless of the nature of the solution.

There are 4 colligative properties: osmotic pressure, decrease in vapor pressure, increase in boiling point and decrease in freezing point.

Answer:

Option (D)

temperature

Explanation:

Colligative properties are the properties that depends on the amount of solute present in a solution, but not on the presence of solute particles.

Since the other three options, freezing point depression, boiling point elevation and lowering of vapour pressure are the colligative properties but the temperature is one that affects colligative properties and is not a colligative property. Increasing or decreasing temperature will not affect the units of concentration, i.e., Molarity, Mole fraction or normality.
