Solution

Sodium lauryl sulphate, $C H_{3} (C H_{2})_{10} C H_{2} O S O_{3}^{-} + N N a$ is an example of anionic detergent.
When added to water, it dissociates as follows
$C H_{3} (C H_{2})_{10} - C H_{2} O S O_{3}^{-} + N N a + H_{2} O - --- \to C H_{3} - (C H_{2})_{10} C H_{2} - O S O_{3}^{-} + + N a$

These anions are present on the surface with their - $O S O_{3}$ groups in water and hydrocarbon part staying away from it and remain at the surface.
At higher concentration. these anions are pulled into the bulk of the solution and form an aggregate of spherical shape with their hydrocarbon pad pointing towards the center. The $O S O_{3}^{-}$ pad outwards on the surface of the sphere.

An aggregate thus formed is known as the micelle.
