The INCORRECT statements below regarding colloidal solutions is :

Options

  1. AA colloidal solution shows colligative properties.
  2. BAn ordinary filter paper can stop the flow of colloidal particles.
  3. CThe flocculation power of Al 3 + is more than that of Na +
  4. DA colloidal solution shows Brownian motion of colloidal particles.

Correct answer

B. An ordinary filter paper can stop the flow of colloidal particles.

Step-by-step 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.
