Answer:
<em>- Since both </em><em>butter and fat are not polar compounds,</em><em> plain </em><em>water (polar) will be unable to clean all the fat from greasy dishes</em><em>.
</em>
<em>- </em><em>What is needed to thoroughly clean a greasy dish is a detergent</em><em>, since it makes it easier for the fat molecules to dissolve in the water.</em>
Explanation:
<u>Water is a molecule considered a universal solvent</u>, given the physical-chemical characteristics that allow it to bind to a large number of molecules and chemical elements as it is a polar molecule. Lipids or fats, on the other hand, are non-polar molecules that cannot be diluted in water, but can be diluted in solvents such as alcohols.
<h3>What happens to greasy plates when dunked in plain water?</h3>
The water (H₂O) is unable to drag the fat molecules on the surface of the plate, which is due to the difference in polarity of the water and fat molecules.
Lipids are non-polar and immiscible molecules in H₂O because they are hydrocarbon chains with single or double bonds that do not show polarity, and their adhesion to the H₂O molecule is not possible.
<h3>What do you need to thoroughly clean a greasy dish and why?</h3>
To remove grease from a greasy dish, a detergent should be applied.
Detergents and soaps are chemical substances that have the property of emulsifying lipids and fats, because they have a hydrophilic portion -with an affinity for water- and a lipophilic one.
When a fat molecule is chemically emulsified it becomes soluble in water -the hydrophilic portion acts with H₂O- which makes it easier for a detergent to facilitate the cleaning of greasy dishes.
