Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The concentration at which micellization occurs
A
Controlled micelle concentration
B
Critical micelle concentration
C
Adequate micelle concentration
D
None of the above
Explanation: 

Detailed explanation-1: -Critical micelle concentration (CMC) is defined as the surfactant concentration at which micelle formation is first seen in the solution.

Detailed explanation-2: -In colloidal and surface chemistry, the critical micelle concentration (CMC) is defined as the concentration of surfactants above which micelles form and all additional surfactants added to the system will form micelles. The CMC is an important characteristic of a surfactant.

Detailed explanation-3: -(9, 10) The minimum concentration of surfactant at which micelles form is termed as “critical micelle concentration” (CMC) and represents one the most important chemical–physical parameters to be determined for these amphiphilic molecules.
