mechanism cleaning action of detergents class 10th

Answer» \tThe molecules of soap are sodium or potassium salts of long chain carboxylic acids.\tA soap molecule has a tadpole-shaped structure.\tAt one end (long non-polar end) of the soap molecule is a hydrocarbon chain insoluble in water but soluble in oil.\tAt the other end (short polar end) of the soap molecule, there is a carboxylate ion, which is hydrophilic, i.e. water soluble but insoluble in oil.\tSoap on mixing with water forms a concentrated solution and causes foaming.\tThe long non-polar end of soap gravitates towards and surrounds the dirt and absorbs the dust in it.\tThe short polar end with the carboxylate ion turns the water away from the dirt.\tA spherical aggregate of soap molecules is formed in the soap solution in water and is called a micelle.\tThe soap molecule thus helps in dissolving the dirt in water and we can wash our clothes clean.
