Lab: Chromatography
1. The water would not have evenly distributed from the starting point, the center, if it were not for the "wick" to transfer the water to the disk-like filter.
2. The pattern of colors produced on the filter paper could have differed due to the difference in the solubility of the ink used, the company who produced the marker/ink, and the type of marker produced.
3. Black ink is composed of many different colors of ink. Thanks to the solubility and molecule size of those different inks and the chromatography paper, we can see each ink clearly after the process is complete.
4. The compounds that are used to make blue could differ, but due to the way this experiment was performed, I could not determine whether the compounds were the same or different. Pigments that were in many of the pens/markers that were tested included blue, a purple-ish pink, and yellow.
5. Only water-soluble pens/markers were used due to the fact that the liquid used to carry out the chromatography process was water. If this experiment were to test the ink in permanent markers, one could use a stronger liquid, such as alcohol.
