Chromatography Lab 1. List an extensive and intensive property of markerink 2. Define Mixture 3. Is tap water an heterogeneous or homogeneous mixture? 4. Is alcohol an heterogeneous or homogeneous mixture? If you were to do this lab with strips of coffee filters, cutinto narrow strips, and with a dot of ink or marker on it,about 3 different marker colors and put it barely into thewater, what would your results be and how fast does the watertravel and how many inches? Distance = distance traveledby compound and distance traveled by solvent? And what is the ratiofor each marker? Do first trial with water, and then second trialwith alcohol? 5. What evidence is there that marker ink is a mixture? 6. Did one compound travel farther then the other? Why? 7. Did the compound travel faster in water or alcohol?Why? 8. How could you improve your measurements?
