Question

Soap remove grease by which process? Coagulation or Adsorption or any other process?

Answer 1

Well soap molecule is made up Na+ions which is hydrophilic and attracts water while the tail is hydrophobic which attracts dirt oil or grease when the cloth is rinsed it helps in removing dirt and this rinsing cleans the dirt

Answer 2

Soap removes grease by the process of adsorption.

Explanation:

A large number of molecular species which is accumulated at the surface of a liquid or solid is called as adsorption. It is basically a surface phenomenon and has several applications.

Grease is made up of fatty acids and glycerine. Soap is formed by hydrophobic and hydrophilic molecules.

When soap is added to water to remove grease, the hydrophilic molecules stay in water whereas the hydrophobic molecules join the oil particles. The oil particles then become suspended in water and disperse into water. The oil particles are removed by the soap molecules by forming micelles with oil particles.
