Question

Explain the action of soaps in removing an oily.spot From a piece of cloth

Answer 1

⭕️Soaps are used for cleaning or removing all the dirts.

⭕️Soap has one polar end which consists with sodium or potassium ion at end and one non-polar end (the end with fatty acid chain).

⭕️The polar end is hydrophilic in nature whose end is attracted towards water. 

⭕️The non-polar end is hydrophobic, it is attracted towards hydrocarbons, but not attracted towards water.

⭕️When soap is dissolved in water, its hydrophobic ends attach themselves to dirt and removes it from the cloth!!!!!!!!


⭕Firstly ️the molecules of soap arrange themselves in micelle formation and trap the dirt they are called micelles. 

⭕️These micelles remain suspended in water. 

⭕️The micelles present in water do not come together since we know that each micelle repels the other because of the ion-ion repulsion.

⭕️Thus, the dust particles remain trapped in micelles are easily rinsed away with water.

⭕️ Hence, soap micelles remove dirt by dissolving it in water.
