Pigments are a substance that gives colour to things, the things that use pigments are felts, paint, plastic, food, fabric and even animals and plants.
Aim- To separate the different pigments from ink using chromatography.
Hypothesis: I think we'll see which pigments more soluble than others and the different colours in the felt.
Equipment- Felt tip pen, filter paper strips, test tube measuring cylinder and 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 it 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
There were different types of pigments in the felt and most of them are soluble.
