Water and methylene chloride are both colorless but immiscible liquids. How could you distinguish between the two if both are present in a separatory funnel?
Homework Answers
Due to the difference in density of the liquid, we can separate liquids in a separatory funnel. Methylene chloride has a density greater than water, so methylene chloride is denser and will settle at the bottom. While water is still above separated by a layer. So we can first take out methylene chloride out and then water.
