and Acetone Soluble Inks through Chromatography Abstract: Chromatography is a term used to define a set of laboratory techniques for the separation of mixtures. Through Chromatography we analyzed complex mixtures. In our recent lab we analyzed complex mixtures. The purpose of this lab was to find whether the water soluble or acetone soluble liquid traveled farther. In our recent lab we measured the distance traveled by the different colored water and acetone soluble inks. W put three dots of
