Question

What are colligative properties? Why is osmotic pressure considered to be a colligative property?

Answer 1

Therefore, any difference in the properties of those two solutions is due to a non-colligative property. Both solutions have the same freezing point, boiling point, vapor pressure, and osmotic pressure because those colligative properties of a solution only depend on the number of dissolved particles.

Answer 2

In chemistry, colligative properties are properties of solutions that depend on the ratio of the number of solute particles to the number of solvent molecules in a solution, and not on the nature of the chemical species present. The number ratio can be related to the various units for concentration of solutions.
Both solutions have the same freezing point, boiling point, vapor pressure, andosmotic pressure because those colligative properties of a solution only depend on the number of dissolved particles. ... Therefore, the taste of the solution is not acolligative property.
