Answer:
- A soap molecule has two parts namely hydrophobic and hydrophilic.
- With the help of these, it attaches to the grease or dirt particle and forms a cluster called micelle.
- These micelles remain suspended as a colloid.
- To remove these micelles (entrapping the dirt), it is necessary to agitate clothes.
