- 1ChromatographyDefinition: Chromatography is a method of separating mixtures, using chromatography paper. It can be used for separating the dyes of a pen, or seeing what pen wrote a particular message. You put a dot of each solvent on a straight line on the paper. Then, after dipping the chromatography paper in water, the solvents travel up the paper, changing colour. It is now easier to distinguish the certain ink. HOWEVER, chromatography can only be used to separate mixtures if all the substances dissolve in one solvent.
- 2DistillationDistillation is another method of separating mixtures. It focuses on different boiling points. A common separation is an ink from water. The process begins by heating the inky water, using a (Micro) bunsen burner. When the water reaches it's boiling point (100 degrees), it begins to bubble, the water gaining energy. The water begins to travel upwards towards the thermometer and down the tube, into the beaker waiting at the end of the tube. The ink from the solution remains inside the round-bottom flask. The solution has now been separated into two different solutes.
