Question
Which of the following is a correct statement?
Options
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.
Solution
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.
