At CMCm the surfactant molecules undergo :

There are cartain substances which behave as normal strong electrolytes at low concentration but at higher concentration they behave as colloidal solutions due to the formation of aggregated particles. Such colloids are called associated coloids and the aggreagated particles are called micelles. Soaps and detergents are the examples of associated colloids. The formation of micelles takes place above certain concentration called critical micrllization concentration (CMC) and a characteristic temperature. Above CMC, the surfactant molecules undergo :

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 aggeregated particles. Such colloidals called associated colloids and the aggeregated particles are called micelles. The formation of micelles take place above certain concentration called critical micelization concentration called critical micellization concentration (CMC) and a characteristic temperature. Above CMC, the surfactant molecules undergo (more than one correct)

At the critical micelle concentration, the surfactant molecules :

The cleaning of dirty clothes by soaps and detergents is due to a type of molecules' called surfactants, which are present in soaps and detergents. The surfactant molecules remove the dirt by

Assertion (A): Micelles are formed by surfactant molecules above the critical micellization concentration (CMC) . Reason(R): The conductivity of a solution having surfactant molecules decreases sharply at the CMC .
