Question

Which of the following is a correct statement?

विकल्प

• Brownian motion destabilises solutions.

• Any amount of the dispersed phase can be added to the emulsion without destabilising it.

• Mixing two oppositely charged solutions in equal amounts neutralises charges and stabilises colloids.

• Presence of equal and similar charges on colloidal particles provides stability to the colloidal solutions.

Answer 1

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

Explanation:

When colloidal particles have similar charges, they repel each other, preventing them from aggregating when they come into contact. As a result, the presence of colloidal particles with equal and similar charges provides stability to colloidal solutions.
