In the context of micelle formation, what is the term used for the minimum concentration of surfactant above which micelles are formed?
- A.Kraft temperature
- B.Critical micelle concentration
- C.Cloud point
- D.Coagulation value
Show correct answer & step-by-step solution
Correct answer: B — Critical micelle concentration
Solution
- Micelles are aggregates of surfactant molecules in solution.
- They form only when the concentration of surfactant exceeds a specific threshold.
- This threshold concentration is defined as the Critical Micelle Concentration.
- The other terms refer to temperature or coagulation properties.
- Hence the answer is (B).
