Experiment 5: Separation of Food Coloring by Paper Chromatography Questions: 1. Do the yellow and blue dyes appear to be composed of a single colored compound? Explain your reasoning. 2. Does the green dye appear to be composed of a single colored compound? Explain. 3. Would it be a problem to use an ink pen or marking pen instead of a pencil? Explain. 4. Consider the molecular interactions that might occur between the dye, the solvent, and the paper. Suggest an explanation for the different Rf values for different dyes. 5. Blue ink from two different pens appears to be the exact same color. Explain how to determine whether the inks are identical
