Science - Chromatography

Hey there, for today I'm going to be separating the colour blue and some black and see what colours are in it.

Hypothesis: I think that the colour blue isn't going to have that much colour. I think that the black is going to have a lot of colours combined together because black is a very strong colour.

Aim:


To separate the different pigments from ink using chromatography

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 IS NOT IN THE WATER.
5- Wait for 5minutes and observe the results
Observation: At first, I didn't see anything happening in the paper. I looked away for a minute then the colours started to separate from each other. The way the colours separated from each other looked really cool. The pigments that was combined together to make the colour Black were some Orange some Blue and a lot of other pigments. I couldn’t remember the other pigments that was in it but it was quite a lot. I also forgot to take a picture of the result that I got bit next time I’ll try to remember it 😊.
