Question

Which one of the following statements is FALSE for hydrophilic sols? 2

(A) Their viscosity is of the order of that of H O
(B) They do not require electrolytes for stability
(C) These sols are reversible in nature
(D) The sols cannot be easily coagulated

Prashant Kotian · Accepted Answer

Correct answer: C) THESE SOLS ARE REVERSIBLE IN NATURE. Hydrophilic colloids are water-loving colloids. The colloid particles are attracted toward the water. They are also called reversible sols. Their surface tension is usually lower than water, due to the breakdown of cohesive forces of the water molecules at the surface. The viscosity of the hydrophilic sols is much higher than that of the dispersion medium.
