Which of the following is not correctly matched with the example mentioned in brackets?
Show Hint
Common colloids:
Smoke \(\rightarrow\) Solid in Gas
Cloud/Fog \(\rightarrow\) Liquid in Gas
Paint \(\rightarrow\) Solid in Liquid
Butter \(\rightarrow\) Liquid in Solid
Updated On: Jun 22, 2026
- Solid dispersed in gas (Smoke)
- Solid dispersed in liquid (Paint)
- Liquid dispersed in solid (Butter)
- Gas dispersed in liquid (Cloud) \bigskip
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Colloids are classified according to the dispersed phase and dispersion medium.
Different combinations produce different colloidal systems.
Step 1: Examine option (A).
Smoke consists of tiny solid particles dispersed in air. \[ \text{Solid in Gas} \] Hence the match is correct.
Step 2: Examine option (B).
Paint contains finely divided solid pigments dispersed in a liquid medium. \[ \text{Solid in Liquid} \] Thus this match is also correct.
Step 3: Examine option (C).
Butter is an emulsion where liquid droplets are dispersed in a solid-like medium. \[ \text{Liquid in Solid} \] Hence this is correctly matched.
Step 4: Examine option (D).
Cloud actually consists of tiny water droplets dispersed in air. \[ \text{Liquid in Gas} \] and not gas dispersed in liquid. Therefore this matching is incorrect.
Step 5: Identify the wrong match.
\[ \boxed{\text{Gas dispersed in liquid (Cloud)}} \] Hence Option (D) is the answer.
