What enables soap to form micelles in water?
1
High temperature
2
Hydrophilic and hydrophobic properties
3
High surface tension
4
Chemical reactions with dirt
Answer and Solution
Answer
B. Hydrophilic and hydrophobic properties
Solution:
Soap molecules have a hydrophilic head that interacts with water and a hydrophobic tail that interacts with oil. In water, they arrange themselves into micelles, where the hydrophobic tails group together in the center and the hydrophilic heads face outward, enabling oil and dirt to be encapsulated and washed away.
