Question

Write short notes on:
Micelle

Hint:

Micelles are essential in soap and detergent action, allowing oils to be washed away with water.

Answer 1

A micelle is an aggregate of surfactant molecules dispersed in a liquid, forming a spherical structure. These molecules have a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail. In aqueous Solution, the hydrophobic tails face inward, trapping grease and oil, while the hydrophilic heads remain in contact with water. Micelles play a crucial role in cleaning, as they help in the removal of dirt and oil from surfaces.
