Identify the correct statements from the following (only one):
I) Sulphur sol is an example of multimolecular colloid.
II) Starch sol is an example of associated colloid.
III) Artificial rubber is an example of macromolecular colloid.
I) Sulphur sol is an example of multimolecular colloid.
II) Starch sol is an example of associated colloid.
III) Artificial rubber is an example of macromolecular colloid.
Show Hint
- I, II, III
- I, II only
- II, III only
- I, III only
The Correct Option is D
Solution and Explanation
- Multimolecular colloids are formed by aggregation of atoms or small molecules; sulphur sol is an example.
- Associated colloids (micelles) are formed by aggregation of amphiphilic molecules; starch sol is not associated colloid, but a suspension.
- Macromolecular colloids consist of large macromolecules; artificial rubber is an example.
Step 2: Evaluate statements
- Statement I: True
- Statement II: False
- Statement III: True
Step 3: Conclusion
Correct statements are I and III only.

- The critical micelle concentration (CMC) of a soap solution is \( 5 \times 10^{-4} \, \text{mol L}^{-1} \). Identify the correct statements about this solution.
[I.] The micelle is stable if the soap solution concentration is \( 10^{-7} \, \text{mol L}^{-1} \)
[II.] The micelle is stable if the soap solution concentration is higher than \( 5 \times 10^{-4} \, \text{mol L}^{-1} \)
[III.] Micelles are also known as associated colloids.- AP EAPCET - 2025
