Question

Surface tension of lyophilic solution is

• A. Lower than water
• B. More than water
• C. Equal to water
• D. None of these

Answer 1

The correct option is A Lower than water

Lyophilic colloids are the colloidal solutions in which dispersed particles have strong affinity for dispersion medium.
This separates the water molecules from each other. Since the surface tension forces become smaller as the distance between water molecules increases, the intervening molecules decrease the surface tension.
