Question

cleansing action of soap with the help of micelle

Answer 1

When soap is dissolved in water then it comes in contact with the oil or dirt particle and then as we know that the head of the soap is hydrophilic and tail is hydrophobic then the tail part get attached to the dirt and form a round structure around the dirt , this structure is micelle and it cleans the dirt from cloth.

Answer 2

Question - Cleansing action of soap with the help of micelle?

ANSWER--

◆ Soap is Sodium (Na) and Potassium (K) salt of carboxylic acids with long chain.

◆ Soaps are effective with soft water only and ineffective with hard water.

◆ Detergent are ammonium or sulphonate salt of carboxylic acids with long chain. They are effective with both soft as well as hard water.


● CLEANING ACTION OF SOAPS ●

◆ Most dirt is oily in nature and the hydrophobic end attached itself with dirt, while the ionic end is surrounded with the water molecules. The result in formation of a radical structure called micelles.

◆ An emulsion is thus formed by soap molecules. The cloth need to be mechanically agitated to remove the dirt particles from the clothes.

◆ SCAM - The Magnesium (Mg) and Calcium (Ca) salts present in hard water reacts with soaps molecules to be insoluble products called Scum, thus obstructing the cleaning structure. Use of detergents overcome the problem as the detergent molecules prevent the formation of insoluble product and thus clothes get cleaned.
