Question

How does soap work? Select one: a. Soap works by having a polar end which attaches to the grease molecule and polarizes it and turns the grease molecule into another soap molecule. This is a chain reaction. b. Soap works by having a polar end and a nonpolar end which allows the water and oil to interact indirectly. c. Soap works by breaking grease molecules into smaller molecules that dissolve in water. d. None of these e. Soap works by making water into a nonpolar liquid which grease can dissolve in

Explanation / Answer

Ans b) Soap works by having a polar end and a nonpolar end which allows the water and oil to interact indirectly.

Soaps are the sodium and potassium salts of long chain of fatty acids .

Which have polar ends on the surface , and hydrophobic tails aligned towards the hydrophobic core .

The hydrophobic core surrounds the grease molecule and the polar ends are attracted by the water molecules that help to pull off the grease molecule from the cloth or fabric .
