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.
If degree of dissociation of an electrolyte, `A_(2)B_(3) "is" 25%` in a solvent, then

Options

A. Normal boiling point = Expermental boiling point.
B. Normal freezing point `gt` Experimental freezing point
C. Normal osmotic pressure = 1/2 Experimantal osmotic pressure
D. Normal molecular mass = 1/4 Exprimental molecular mass
