Chromatography

• Chromatography is used to separate homogeneous mixtures and the concepts of solubility and density.
• Standard ink goes from bottom to top.
• Radial ink goes from center to side.
• Pure Substances will only show one pigment.
• Mixtures will separate into more than one spot.
• Higher/Farther from the solvent is more soluble.
• Lower/Closer to the solvent is less soluble.
