5. You identified the most and the least travelled dyes, and the most and least polar solvents. What causes the components to separate? Based on these observations and using the concept of LIKE DISSOLVES LIKE" identify Page | 159 a. Which of the dyes is the most polar? Why? b. The least polar? Why? 6. How many components were in the dye mixture that you used? Is the manufacturer of the pen used a single color ink or a mixture of different color inks? 7. Name two practical uses for the paper chromatography phase. One spot substance is re-analyzed using solvent B as the mobile phase. This time, two spots are obse after the plate is developed and visualized. Is the unknown sample a pure substance or a minture? Explain. d visualized. The same unknown 8. An unknown liquid sample is analyzed using paper chromatography using solvent A as the mobile
