Describe the cleansing action of soap |
|
Answer» \tWhen soap is dissolved in water, its hydrophobic ends attach themselves to dirt and remove it from the cloth.\tFirst, the molecules of soap arrange themselves in micelle formation and trap the dirt at the centre of the cluster.\tThese micelles remain suspended in water like particles in a colloidal solution.\tThe various micelles present in water do not come together to form a precipitate as each micelle repels the other because of the ion-ion repulsion.\tThus, the dust particles remain trapped in micelles (which remain suspended) and are easily rinsed away with water.\xa0\tHence, soap micelles remove dirt by dissolving it in water. Cleansing Action Of Soaps\xa0And Detergents. ... The molecule of\xa0soapconstitutes sodium or potassium salts of long chain carboxylic acids. In the case of\xa0soaps\xa0the carbon chain dissolves in oil and the ionic end dissolves in water. |
