Background Information: Paper Chromatography is a separation tool in which pigment is put on a paper made of cellulose and water, and placed in a solvent, in this case isopropyl alcohol. Due to capillary action, the solvent crawls up the paper, separating the pigments. This technique is used to identify components of a mixture, even unknown ones, and can be used to isolate components into pure samples. Real world uses of this technique includes identifying certain biomolecules by pigmenting certain regions of the sample, is used in forensic sciences t analyze DNA and RNA sequencing, and is used in organic chemistry to identify unknown compounds.…
