Polarity is a characteristic of molecules that making the charges unequally distributed causing it to create a magnetic field. One way you can check if a substance is polar or not is by doing the High Performance Chromatography Lab. Using water, different percentages (5%, 20%, and 60%) of methanol and isopropyl alcohol, Kool-Aid, and a syringe with a C-18 cartridge attached. Putting the Kool-Aid through first, made the dye stay in the cartridge, and the liquid turned clear. Next, putting the methanol alcohol, from lowest to highest percentage, made the solution turn a shade of yellow, pink, and blue. After, redo the steps now with the methanol. From decreasing to increasing percentage, it let out a light red, light purple, and blue solution.
