Q.
Abnormal colligative properties are observed only when the dissolved non-volatile solute in a given dilute solution
J & K CETJ & K CET 2008Solutions
Solution:
As the colligative properties depend only upon the number of particles of solute, so if the non-volatile solute dissociates or associates in the solution, the value of colligative properties deviates ie, abnormal colligative properties are obtained.
