Question

Give explanation of micelle. Explain critical rnicelle concentration.

Answer 1

Answer:

A micelle is a type of colloid which is mainly formed by any surfactant in equilibrium with other molecules or ions.

For example: lipid molecules when placed in aqueous solution form micelles.

The critical micelle concentration can be defined as the concentration of surfactants at which the micelle formation particularly takes place spontaneously.

Answer 2

$\huge \fbox \red{Answer}$

The CMC (critical micelle concentration) is the concentration of a surfactant in a bulk phase, above which aggregates of surfactant molecules, so-called micelles, start to form. The CMC is an important characteristic for surfactants.
