Question

Lyophilic sols are more stable than lyophobic sols because ______.

Options

• then is a strong electrostatic repulsion between the negatively charged colloidal particles.

• the colloidal particles have positive charge. 

• the colloidal particles have no charge. 

• the colloidal particles are solvated.

Answer 1

Lyophilic sols are more stable than lyophobic sols because the colloidal particles are solvated.

Explanation:

Colloids known as lyophilic sols have a strong attraction for both the dispersion medium and the particles of the dispersed phase. The colloidal particles are heavily solvated in lyophilic colloids.
