    Resolution of Matter into Pure Substances – Paper Chromatography Abstract The purpose of this laboratory was to determine how different substances have different solubilities in a given solvent. This was accomplished using the method of chromatography. The solubility of each substance was first determined by dropping a drop or two of each on a line drawn 2 inches above the bottom of a piece of paper. Then the paper was lightly bent in order to tape both sides of the paper leaving about a 4 centimeter
