Q17 / 90 · JEE Main 2021 (16 Mar Shift 2) · Chemistry

The INCORRECT statements below regarding colloidal solutions is :

A
A colloidal solution shows colligative properties.
Correct answer
B
An ordinary filter paper can stop the flow of colloidal particles.
C
The flocculation power of ${Al}^{3 +}$ is more than that of ${Na}^{+}$
D
A colloidal solution shows Brownian motion of colloidal particles.

Solution

* Colloidal solution exhibits colligative properties

* An ordinary filter can not stop the flow of colloidal particles.

* Flocculation power increases with increase in the opposite charge of electrolyte.

* Colloidal particles show Brownian motion.

Hence, the correct answer is option: 'B'.
