Today we learnt what Chromatography and did a little experiment.
What is Chromatography? Chromatography- the process of separating a mixture based on the pigments.
Pigments- Pigments can be separated based on their solubility. More soluble the pigment the higher they move with the water. The less soluble the lower they will stay on the chromatography paper.
AIM- To separate the different pigments from ink using chromatography
HYPOTHESIS- I think that it will change colour.
EQUIPMENT- Felt tip pen, filter paper strips, test tube, measuring cylinder, pencil.

Method-
1- Draw a line across the filter paper in pencil, 5cm from the bottom.
2- Draw a coloured dot in the centre of the line.
3- Measure out 10mL of water and place in the test tube.
4- Place the filter paper in the test tube and fold over the side. MAKE SURE THE PENCIL LINE/ DOT IS NOT IN THE WATER.
5- Wait for 5 minutes and observe the results
