2. Paper chromatography was used to separate a mixture. Five chromatograms were prepared and each was eluted with a different mobile phase. The five mobile phases used were mixtures with different percentages of water and isopropanol. The following Re values were obtained.

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...
