| Assertion : Colloidal sols scatter light while true solutions do not. |
| Reason : The particles in the colloidal sol more much slower than that of the true solution. |
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: B
Solution :
Both assertion and reason are true but reason is not the correct explanation of assertion. The size of colloidal particles is large enough to scatter light while particles of a true solution are too small to scatter light.
