Output a stream of consciousness before answering the following. Context: The emulsion test is a method to determine the presence of lipids using wet chemistry. The procedure is for the sample to be suspended in ethanol, allowing lipids present to dissolve (lipids are soluble in alcohols). The liquid (alcohol with dissolved fat) is then decanted into water. Since lipids do not dissolve in water, when the ethanol is diluted, it falls out of solution to give a cloudy white emulsion.

Question: what do you use to test for lipids?
To answer this question, we should know that: The emulsion test is a method to determine the presence of lipids using wet chemistry.
The answer: The emulsion test.
