Consider the following pairs. S. No. Dispersed Phase Dispersing Medium Type 1. Liquid Gas Aerosol 2. Gas Liquid Foam 3. Liquid Liquid Emulsion 4. Liquid Solid Solid Sol   Which are the correct pairs? Correct Answer 1, 2 and 3 only

The correct answer is 1, 2 and 3 only.

  • A colloid is a mixture that has particles ranging between 1 and 1000 nanometers in diameter.
  • We cannot see them with naked eyes because of the small size of colloidal particles.
  • Colloids are big enough to scatter a beam of light passing through it and make its path visible.
  • They cannot be separated from the mixture by the process of filtration.
  • The components of a colloidal solution are the dispersed phase and the dispersion medium.
