Question

Quizplus · Accepted Answer

Soap has a polar end (hydrophilic) and a nonpolar end (hydrophobic). When soap is added to water, the polar end is attracted to the water molecules while the nonpolar end is repelled by the water molecules. When oil is present, the nonpolar end of the soap molecules will surround the oil droplets, creating a micelle with the nonpolar end of the soap molecules facing inward and the polar end facing outward. This allows for the oil droplets to be suspended in water and easily removed.
