I did an experiment in class on Chromatography and extracting pigment material from a leaf and such.
We took a piece of some special paper put a base line in pencil at the bottom and covered it with leaf extract. Then putting a pin through the top set it in a beaker of acetone and the chemicals rose to the top.
Anyway how does Chromatography work? Trying to answer some questions but I can't seem to find the type of answer I'm supposed to have.
I said to the teacher: The surface area in the beaker is lowered when the paper is put inside and forced the materials up. He said I was on the right track with that but it wasn't right.
Also carotone, chlorophyll A & B, and Xanthrophyl were chemicals apparent at the top of the paper. I took the Rf values and such.
Anyway I'm suppose to answer what were the roles of carotene and xanthrophyl. I have no clue lol. There is so much stuff of Chromatography on the net its hard to find what I'm looking for. And yes I do pay attention in class. ;)
Thanks to anyone who can help me out here.
