Extraction is a method used for separating and isolating materials. A compound is pulled from solvent A to solvent B and in this case‚ both solvents are miscible. These two concepts are not capable of mixing together; when they are mixed together‚ they form a bilayer. This can be seen when mixing oil and water together. When thinking of extractions‚ one can picture how coffee gets extracted. The flavors‚ molecules‚ caffeine‚ etc. are extracted from the coffee beans. In this experiment‚ a solution
