• A. A colloidal solution shows colligative properties.
• B. An ordinary filter paper can stop the flow of colloidal particles.
• C. The flocculating power of $A{l}^{3+}$ is more than that of $N{a}^{+}$.
• D. A colloidal solution shows Brownian motion of colloidal particles.

Answer 1

Answer: (B)

* Colloidel solution exhibits colligative properties

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

* Flocculating power increases with increase the opposite charge of electrolyte.

* Colloidal particles show brownian motion.
