Which of the following statements is NOT TRUE in respect of hydrophilic sols?
Which of the following statements is NOT TRUE in respect of hydrophilic sols?
- A. They are quite stable and are not easily coagulated
- B. There is considerable interaction between dispersed phase and dispersion medium (water)
- C. The sol particles are hydrated
- D. They are very sensitive to coagulation by a small concentration of electrolytes
Step-by-step solution
Hydrophilic sols are lyophilic colloids that are stabilized by hydration and strong interactions with water. They are resistant to coagulation and require large concentrations of electrolytes to coagulate, not small amounts. Therefore, statement D is false.
