Which is not the property of hydrophilic sols ?

A

High concentration of the dispersed phase can be easily attained.

B

Coagulaton is reversible.

C

The charge on the particles depends on the pH value of the dispersion medium.

D

Viscosity and the surface tension are the same as of the dispersion medium.

Text Solution

Verified by Experts

The correct Answer is:
D
In hydropilic sol, there is a high concentration of the dispersed phase in water. As a result, the viscosity of the hydrophilic sol is higher than that of the d ispersion medium (water) while the surface tension is less.
