Which of the following statements is incorrect about colloidal solution?

Options

  1. ALyophobic sols are more stable than lyophilic sols.
  2. BLyophilic colloids have a unique property of protecting lyophobic colloids.
  3. CLyophilic colloids are highly hydrated than lyophobic colloids.
  4. DNone of these.
