Question

Cleansing action of soaps includes:

• A. formation of micelles
• B. emulsification of oil or grease
• C. lowering of surface tension of water
• D. all of the above

Answer 1

The correct option is D all of the above

According to the given image, when soaps or detergents are dissolved in water, micelle formation takes place as the surfactant ions orient themselves with grease and water. Then, agitation begins to separate the grease from surface of clothes, which lowers the surface tension of water.

Thus, Option D is correct.
