WebChromatography is a method for separating dissolved substances from one another. It works because some of the coloured substances dissolve in the solvent better than others, so they travel further up the paper. This technique is often used to separate out inks, or food colourings. Paper chromatography consists of two stages: WebDraw a line (in pencil) across a piece of chromatography paper, about 1 cm above the bottom. Place a spot of the new pen's ink from the pen on the pencil line, and place a spot of the original ink on the line. Hang the piece of paper in a beaker, and add a small amount of solvent (not water, e.g. ethanol) as to not cover the pencil line. WebRequired Practical 6: Chromatography ... GCSE Chemistry Paper 2.
