When applied to a dish, soap makes grease soluble in water. which explanation correctly supports the role of intermolecular forces in this common observation? the nonpolar end of a soap molecule attaches itself to grease. the nonpolar end of a soap molecule attaches itself to water. the polar soap molecule attaches itself to the dish. the polar soap molecule attaches itself to a nonpolar soap molecule.
THIS IS THE BEST ANSWER ๐
Explanation:
Soaps bind to water and grease molecules.
The stronger fat molecules are attracted towards each other compared to water molecules. Also, water molecules are smaller in size therefore a strong intermolecular force is required to break the hydrogen bonds of the water molecule so that grease or oil molecules can enter the water molecule.
A molecule of soap passes between water and a molecule of grease and helps them bind. The force for bonding between a molecule of water and grease through the soap molecule is a weak London scattering force.
The soap molecule has a salt end as an ionic and water soluble. When grease or oil is added to the soap and water solution then the soap acts as an emulsifier. The soap creates miniatures of the non-polar tails and fat molecules are trapped between these misconceptions. This miscelle is readily soluble in water therefore the grease is washed off.
Thus, it can be concluded that the nonpolar end of a soap molecule binds to grease.
