Answer:
1. Soaps have an ionic part called as hydrophilic Head and other which is part of a carbon chain called hydrophobic end.
2. Most of the dirt particles are oily in nature and thus are stuck to the soap molecules easily in such a way that:
3. The hydrophobic and of soap molecules surrounds the dirt particle whereas hydrophilic and is surrounded by water
4. this from a radial structure of soap molecules around the dirt called Micelle.
5. these micelles are dissolve in water along with the dirt to form emulsion of water and soap molecules.
6. Thus washes away our clothes clean.
7. In hard water there is more concentration of Ions (calcium and magnesium) which react with soap molecule to form scum, an insoluble substance.
8. This acts as a barrier in cleaning action of soaps.
9. Therefore, the soaps are more efficient in soft water
