Question
Why is soap mixed with water?A.The soap turns the water molecules into a nonpolar solvent.B.It covalently bonds to the water so it can be washed away.C.The soap becomes chemically active when mixed with water.D.Its polar end mixes with the water so it can be washed away.
Solution
Soap is mixed with water because its polar end mixes with the water so it can be washed away. This is due to the molecular structure of soap, which has a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail. When soap is mixed with water, the hydrophilic heads are attracted to the water, and the hydrophobic tails are repelled, creating micelles. These micelles can trap dirt and oil, which can then be rinsed away with water. This is the basic principle behind the cleaning action of soap.
