Answer:

CLEANSING ACTION OF SOAP. - Teachoo.jpg

  • Since the soap molecule has two ends that are the hydrophobic and the hydrophilic end , when it dissolves in water, it forms a special orientation known as micelle . 
  • In this, the hydrophilic part remains on the surface of the cluster and the hydrophobic part is towards the interior . 
  • In the form of this micelle, soap is able to clean because the oily dirt gets collected in the middle of the micelle . 
  • They stay in the solution as a colloid and do not come together because of the ion-ion repulsion. Thus, the dirt suspended in the micelles is also easily rinsed away.
