When a sulphur sol is evaporated, sulphur is obtained. On mixing with water, sulphur sol is not formed. The sol is
- A hydrophilic
- B hydrophobic
- C reversible
- D lyophilic
Answer & Solution
Correct Answer
(B) hydrophobic
Step-by-step Solution
Detailed explanation
When a sulphur sol is evaporated, sulphur is obtained. On mixing with water, sulphur sol is not formed. The sol is liydrophobic. Ilydrophobic sols are irreversible in nature. There is a little affinity between the dispersed phase and the dispersion medium.
