Question

CMC (Critical Micelle Concentration) is:

• A. concentration at which micelles are destroyed
• B. concentration at which micelles formation starts
• C. concentration of electrolyte added to destroy the micelles
• D. concentration of micelles at room temperature

Answer 1

The correct option is B concentration at which micelles formation starts

The micelles are formed by the association of dispersed particles above a certain concentration above which the process of aggregation to take place. The minimum concentration required for micelle formation is called critical micelle concentration (CMC)
