At Critical Micell Concentration (CMC), the surfactant molecules :
Open in App
Solution
The correct option is B associate
Micelles are relatively small, spherical structures composed of a few to few thousand molecules that attract one another to form larger aggregate which falls in colloidal range.
Micelles are formed by aggregation of small molecules. Thus, they are also known as associated colloids.
Eg. Soap in water, detergent in water.
Soap and detergent are called surfactants.
The critical Micelle Concentration (CMC) is the concentration of surfactants in a solution above which micelles form. Below the CMC, surfactants in solution adsorb to a surface, lowering the surface tension. Above the CMC, the vast majority of added surfactant will form micelles.
