Question

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

• A. These sols are reversible in nature
• B. The sols cannot be easily coagulated
• C. They do not require electrolytes for stability
• D. Their viscosity is of the order of that of $H_{2}O$

Answer 1

The correct option is D Their viscosity is of the order of that of $H_{2}O$

The viscosity of hydrophilic sol is much greater than that of their dispersion medium i.e., $H_{2}O$.
