To separate the different pigments from ink using chromatography

Equipment: 

1. 250 ml beaker

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 10 mL 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 IS NOT IN THE WATER.

5- Wait for 5 minutes and observe the results

results:

I decided to use red it reached out through the paper there was a little tint of orange but mainly red.

Second time I used black the pigments in black are black, orange, purple, pink and blue.

In Social Studies we had to do a timeline on 9/11 and the tragedy's that happened. The tragedy's were about an American Airline plane that crashed into the world trade centre
