Question
Micelles in the soap are
- The carbon chain of soap is inside the cluster, while the ionic end is on the cluster's surface.
- The soap's ionic end is inside the cluster, but its carbon chain is outside of it.
- Both the soap's ionic end and carbon chain are inside the cluster.
- The cluster's exterior is covered by both the ionic end and the carbon chain.
Hint:
The hydrophobic end is on the inside of clusters.
The correct answer is: The carbon chain of soap is inside the cluster, while the ionic end is on the cluster's surface.
- Micelles in the soap are The carbon chain of soap inside the cluster, while the ionic end is on the cluster's surface.
- When soap is applied to a damp, dirty surface, the polar end of the soap molecule dissolves in water and the non-polar end binds it to the dirt molecule.
- This is because dirt is inherently non-polar. This results in the formation of spherical clusters called micelles.
- In micelles, the hydrophobic ends are on the inside of the clusters and the ionic ends are on the surface of the clusters.
