Question

Which one are examples of solid sol?

• A. Alloys
• B. Ruby Stone
• C. Vision Glasses
• D. All of these

Answer 1

The correct option is D

All of these

Explanation for the correct option

(D) All of these

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.
