Question

Action of soap is due to emulsification and micelle formation. Comment.

Answer 1

The cleansing action of soap is due to emulsification and micelle formation.Soaps are basically sodium and potassium salts of long chain fatty acids, R-COO-Na+. ... This is known asmicelle formation. Thus, we can say that the polar group dissolves in water while the non-polar group dissolves in the dirt particle.

Answer 2

Answer:

The cleaning action of soap is due to emulsifiacation and micelle formation

Explanation:

Soaps are basically stadium and potassium salts of long chain fatty acid R-COOminus Na+

The end to the molecule to which the sodium is attached is polar in nature, while the alkyl end is non polar. This a salt molecule contain a hydrophobic and hydrophilic part.

When soap is added to water containing dirt the soap molecule surrounded the dirt particle in such a manner that their hydrophobic part is attached to dirt particle and the hydrophilic part away from the dirt particle known as micelle formation. Which means hydrophilic part is attached to water and hydrophobic part is attached to dirt.Now these molecules are negatively charged they do not coalesce and stable emulsion is formed
