Soap removes grease stains from fabric primarily by which mechanism?

1. Adsorption
2. Emulsification
3. Coagulation
4. None of these

Correct answer: Emulsification

Solution

Soap molecules have a hydrophobic (non-polar) tail that dissolves in grease and a hydrophilic (ionic) head that stays in water. This allows soap to form micelles around grease particles, creating an emulsion that can be rinsed away.
