Question

explain cleaning action of soap with the help of micelles.

Answer 1

ANSWER---

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

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

◆ Scum - The Magnesium and Calcium salts present in hard water reacts with soap molecule to form insoluble product is called scum, thus obstructing the cleaning action. Use of detergents overcome this problem as the detergent molecule prevent the formation of insoluble product and thus clothes get cleaned.

Answer 2

${\huge{\mathfrak{Answer:-}}}$

$<b><u>$Cleansing action of soaps:

The dirt present on clothes is organic in nature and insoluble in water. Therefore, it cannot be removed by only washing with water. 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. Hence, the dust particles are easily rinsed away by water.
