प्रश्न
Explain their cleansing action?
उत्तर
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.
