Want this question answered?
it produces a brick/dark red stain.
The sudan dye is a lipid itself, therefore you have a lipid layer interacting with another lipid.
because it want to show that Sudan iv is soluble in water n not soluble when there is lipid presence . From there you can make lipid as your responding variable
Sudan IV is only soluble in certain solvents.
Sudan IV is a diazo dye for staining lipids, lipoproteins, and triglycerides. It is used in Sudan staining, wherein it attaches to the fats chemically.
if i understand wat you are asking the answer is lipids.
Sudan dye is lipid -soluble dye, thus, it will turn any lipids to red. It mixes with it.
If no lipids are present, the red dye will sink to the bottom of the test tube. Sudan (iv) is not soluble in water but soluble in lipid.
