Question:
What type of collodial system is milk?
What type of collodial system is milk?
Show Hint
Milk is made of tiny liquid fat droplets spread in water, which is a liquid dispersed in a liquid.
Updated On: Nov 12, 2026
- Sol
- Emulsion
- Gel
- Aerosol
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
A colloid is classified by the physical states of its dispersed phase and dispersion medium.
Step 2: Apply to milk
In milk, liquid fat globules are dispersed in water, so both the dispersed phase and the medium are liquids.
Step 3: Name the system
A liquid dispersed in a liquid is called an emulsion, whereas a sol has a solid in a liquid, a gel has a liquid in a solid and an aerosol has a solid or liquid in a gas.
Final Answer:
Milk is an emulsion. \[ \boxed{\text{(B) }\text{Emulsion}} \]
