Aim: To separate the different pigments in ink or dyes using paper chromatography
Method: 1. Cut a strip of filter paper that is long enough to reach the bottom of your beaker.
2. Fill your beaker with enough chromatography solution to fill you beaker to a depth of 10cm
3. Place a dot of ink above the ruled line on your paper. you need to produce a concentrated dot of ink so repeated applications may be necessary.
4. Wait to see what happens. It is important that you do not disturb the beaker. If the solution come in contact with the ink dot, the ink will run down into the solution rather than move up the filter paper
Results: They turned out very well some of mine failed because the ink got into the solution and different colours I tried out did not do as well as other colours.
Discussion: When the solute is to low and the solvent is to high it wont work. The water will soaked the paper an it wont turn out the way you want it to.
If the solute and solvent / solution work well you could try different colours different patterns eg
