Please help me better understand and complete this lab.
I think i may have made an error on the paper chromatography, but I’m not sure. I thought the red #40 should have been more polar than the yellow, but it looks to have ran off the page. I’m confused about what to write for the polarity of the three.
The peak wave length values I obtained correspond to color ranges that don’t seen to match the colors I saw in the tubes. I need help with the identity and reference literature.
Any suggestions for possible sources of error would also be helpful. Thanks!
