Which of the following is a correct statement?

Which of the following is a correct statement?

Options

  1. ABrownian motion destabilises sols.
  2. BAny amount of dispersed phase can be added to emulsion without destabilising it.
  3. CMixing two oppositely charged sols in equal amount neutralises charges and stabilises colloids.
  4. DPresence of equal and similar charges on colloidal particles provides stability to the colloidal solution.

Correct answer

D. Presence of equal and similar charges on colloidal particles provides stability to the colloidal solution.

Step-by-step solution

As equal & similar charge particle will repel each other, hence will never precipitate. So, the option D is correct.

Mixing two oppositely charged sols in equal amount neutralises charges and as a result colloids precipitate.

Only a certain amount of dispersed phase can be added to emulsion without destabilising it.

Brownian motion stabilises sols.
