Question:
Which of the following colloidal system represents a gel?
Which of the following colloidal system represents a gel?
Show Hint
Remember that gels exhibit semi-solid characteristics because the liquid is trapped within a solid network.
Updated On: Jun 9, 2026
- Solid in liquid
- Solid in gas
- Liquid in solid
- Liquid in gas
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Colloidal systems are classified based on the physical state of the dispersed phase and the dispersion medium. A gel is a type of colloidal system where a liquid is dispersed in a solid medium.
Step 1: Analyze the classification of colloidal systems.
The classification for various systems is as follows:
• Solid in liquid: Sol
• Solid in gas: Aerosol
• Liquid in solid: Gel
• Liquid in gas: Aerosol
Step 2: Conclusion.
Since a gel consists of a liquid phase dispersed within a solid phase, option (C) is the correct representation. \[ \boxed{\text{Liquid in solid}} \]
