Question

At Critical Micell Concentration (CMC), the

surfactant molecules:

(A) decompose

(B) dissociate

(C) associate

(D) become completely soluble​

Answer 1

HEYA!
______

At Critical Micell Concentration (CMC), the surfactant molecules:

become completely soluble.

________

Answer 2

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, or disperse eithin the bulk. There may be an occasional micelle formed below the CMC. Likewise, above the CMC, a very limited amount of added surfactants may enter the dispersed phase or adsorb onto an interface. However, above the CMC, the vast majority of added surfactant will form micelles.

So the right answer is - become completely soluble
