Which structure do soap molecules form around oily dirt in water?
Answer and explanation
Correct answer: Micelle
The hydrophobic end of a soap molecule faces the oily dirt, while the hydrophilic end faces the water. Many soap molecules surround the dirt and form a micelle. This disperses the dirt in water so that it can be washed away. An emulsion is a mixture of two immiscible liquids, whereas the specific structure formed around dirt by soap is a micelle.
