Solid sol

  • A solid sol is a colloidal solution in which both the dispersion medium (solvent) and the dispersed phase (solute) are solid.
  • A heterogeneous combination of tiny particles of one substance dissolved in another is referred to as a colloidal solution.
  • The substance in the solution that is distributed is known as the dispersed phase.
  • The medium in which the dispersed phase is dispersed is known as the dispersion phase.

(A) Alloys

  • A metal is fused together with other metals or non-metals to form an alloy, which is a homogeneous mixture.
  • Alloys may be considered as solid sols where the solute is the metal, and the solvent is the metal with a high concentration.
  • One such alloy is brass, which is made of copper (solvent) and zinc (solute).
  • It is an example of a solid sol.

(B) Ruby Stone

  • Both the dispersion medium and the dispersed phase are solid in ruby stone.
  • It is an example of a solid sol.

(C) Vision Glasses

  • Cooling molten glass causes it to flow more slowly until it eventually becomes almost solid.
  • It is an example of a solid sol.

Explanation for incorrect options

  • All the options (A), (B) and (C) are correct.

Therefore, the correct option is (D) All of these.
