Options

  1. Ahydrophilic
  2. Bhydrophobic
  3. Creversible
  4. Dlyophilic

Correct answer

B. hydrophobic

Step-by-step solution

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.
