There are certain substances which behave as normal, strong electrolyte at low concentration but at higher concentration they behave as colloidal solutions due to the formation of aggregated particles. Such colloids called associated colloids and the aggregated particles are called micelles. The formation of micelles take place above certain concentration called critical micellization concentration (CMC) and a Kraft temperature.
Above CMC, the surfactant molecules undergo (more than one correct)

A

Decomposes

B

Become completely soluble

C

Associate

D

Dissociate

Text Solution

Verified by Experts

The correct Answer is:
C
Association occurs at CMC so colloid is formed
