Q. Which is not a property of hydrophilic sols?
A) High concentrations of dispersed phase can be easily attained
B) Coagulation is reversible
C) Viscosity and surface tension are about the same as of dispersion medium
D) The charge of the particle depends on the pH values of the dispersion medium; it may be positive, negative
Explanation
(c)
Viscosity of hydrophilic is much higher than dispersion medium. Surface tension being much lesser than dispersion medium (water). This is due to higher concentration of dispersed phase in water due to water loving nature.
