Question

Explain in brief cleaning action of soaps & detergents with the help of diagram.

Answer 1

Answer:

Cleansing action of soaps: ... When soap is dissolved in water, its hydrophobic ends attach themselves to the dirt and remove it from the cloth. Then, the molecules of soap arrange themselves in micelle formation and trap the dirt at the centre of the cluster. These micelles remain suspended in the water.

Answer 2

Cleansing action

Explanation:

Soaps are sodium (Na) salts or Potassium (K) salts of some long chain carboxylic acids (COOH) but detergents are ammonium or sulphurated salts of COOH. When a dirty cloth with an oily spot is put in water containing dissolved soap, the oil is not dissolved in water. The acid end of soap is hydrophilic and gets dissolved in water and the carbon chain dissolves in oil. Soap forms a micelles structure in which one end of the soap molecule is attached to the oil droplet and the other end towards the water. The formation of soap micelles thus removes oil from the shirt.
