Answer:
Ethanol is known as a fat solvent, and the cloudy or white color that it acquires when testing fat is due to the fact that this test includes the addition of water, forming an emulsion.
Explanation:
<u>The emulsion test for fats</u> is a test used to show the presence of these in some substances or foods.
Under normal conditions, fats are miscible - they can be dissolved - in ethanol, an alcohol, but not in water.
This test consists of dissolving the substance to be tested in ethanol, and then adding water. The principle by which the emulsion test is governed is that ethanol allows a certain amount of fat to dissolve in water, forming a cloudy or whitish emulsion.
