explain the cleaning action of soap
Answers
Answer:
When soap is dissolved in water, its hydrophobic ends attach themselves to dirt and remove it from the cloth. First, the molecules of soap arrange themselves in micelle formation and trap the dirt at the centre of the cluster. These micelles remain suspended in water like particles in a colloidal solution.

The cleansing action of both soaps and detergents results from their ability to lower the surface tension of water, to emulsify oil or grease and to hold them in a suspension in water.
This ability is due to the structure of soaps and detergents.
In water, a sodium soap dissolves to form soap anions and sodium cations. For example, the following chemical equation shows the ionisation of sodium palmitate.

The dirt present in a clothes is organic in nature and insoluble water.
