Question

Explain the cleaning action of soaps.

Answer 1

Soap are cleansing agents which are capable of reacting with water to dislodge the unwanted particles from clothes or skin. The molecules of soap r sodium or potassium salts of long chain carboxylic acids A soap has a tadpole shaped structure .At one end of dope molecule is a hydrocarbon chain i.e insoluble in water but not in oil . At other end of soap molecule there is a carboxylate ion which is hydrophilic i.e water soluble but not soluble in oil . When soap is mixed with water , the solution caused becomes concentrated and causes foaming.

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.
