Chemistry Question on Solutions
Abnormal colligative properties are observed only when the dissolved non-volatile solute in a given dilute solution
A
is a non-electrolyte
B
offers an intense colour
C
associates or dissociates
D
offers no colour
Answer
associates or dissociates
Explanation
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.
