Chromatography: Separating Mixtures Introduction: Magic marker inks are often mixtures of several compounds. Paper chromatography is a common method of separating various components of a mixture. After separation, you can observe the different colors that make up a particular color of magic marker ink. You can also calculate a ratio Rf, which compares how far each compound traveled to how far each solvent (substance that dissolves another substance) traveled during the experiment. Rf = Ds/Df Ds = Distance traveled by the compound Df = Distance traveled by the solvent Materials: c

Post-Lab Questions:
 
What evidence is there that marker ink is a mixture? 
 
 
 
 
Each compound in the marker ink is represented by a color. Did one compound travel farther than the others? Explain why you think that this is the case.
 
 
 
 
 
Did the compounds travel farther in the water or the isopropyl alcohol (rubbing alcohol)? Explain why you think that this is the case.
 
 
 
 
 
 
How could you improve upon the accuracy of your Rf measurements?
