In respect to this, is viscosity a 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. Other non-colligative properties include viscosity, surface tension, and solubility.

Beside above, is Vapour pressure a Colligative property? 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.

Regarding this, what are the 4 Colligative properties?

The four commonly studied colligative properties are freezing point depression, boiling point elevation, vapor pressure lowering, and osmotic pressure. Since these properties yield information on the number of solute particles in solution, one can use them to obtain the molecular weight of the solute.

Which is not a Colligative property?

Colligative properties are the properties which depend upon the number of solute particles present in the solution. Optical activity does not depends upon number of particles present hence it is not a colligative property. Hence, option B is the answer.
