Question

describe cleansing action of soap

Answer 1

The hydrophillic part disolves in water and the hydophopic part will dissolves in the oil or dirt.Then the soap forms clusters of molecules in which the the hydrophobic tails are in the interior of the cluster and hydrophillic ends are on the surface of the clusters.This formation is called micelles.Thus the dirt is in the centre of the micelle and are easily rinsed away

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.
