  • An example of colligative property is

    A
    Freezing point
    B
    Boiling point
    C
    Vapour pressure
    D
    Osmotic pressure

  • The exprimental values of colligative properties of many solute in solution resemble calculatede value of colligative properties. However in same cases, the expermental value of colligative property differ widely form those obtained by calculation. Such experimental values of colligative properties are known as abnormal values of colligative propertiy. Cause for abnormal values of colligative properties are : Dessiation of solute : It increases the colligative properties. Association of solute : It decreases the colligative properties. Choose the correct answer. (19) One mole I_(2) (solid) is added in !M, 1 litre KL solution, Then

    A
    Osmotic pressure of solution increases
    B
    Freezing point of solution increases
    C
    Rrlative lowering in vapour pressure decreases
    D
    No change in boiling point of solution.
