Chromatography Experiment

Chromatography

Aim: To separate colours by using the process of chromatography.

Definition: A technique for separating the different parts of a mixture/solid using liquid. 

Materials:

1. Filtered Paper

2. Ruler

3. Green Felt Pen

4. Black Felt Pen

5. Red Felt Pen

6. Container/Cup

7. Pencil

8. Liquid

Process:

Step 1: Get your filtered paper and rule up a 2 cm pencil line on the top.

Step 2: Rule a 1 cm pencil line on the bottom.

Step 3: Get your black, red, and green felts, make a dot for black on the 1cm line same with red and green.

Step 4: Fold your filtered paper on the 2cm line. 

Step 5: Get your container/cup, and place the folded part of the filtered paper on the top of the cup.

Step 6: Pour a little amount of liquid/water for the filtered paper to absorb.

Step 7: Watch the colours rise up to the paper and you should see what colours are inside of the specific colours.

Findings & Reflection: 

I found out that black and green had a blue colour at the end but the colour red pretty much stayed the same colour. So I think that red had the least colours inside which was red and a bit of pink. Green had the second lest colours and they were blue, yellow and a little bit of green in the middle. Black had the most, it had pink, orange, red, blue, and a little bit of black which is also in the middle. 

 I did the same thing, but with different colours. I chose the colours orange, pink, and yellow. When it started rising there weren't many different colours appearing. They were still orange pink and yellow. Also when I was doing this experiment I thought of something. Maybe darker colours give more colours than lighter colours. That's why when I did orange, pink, and yellow not much colours came appeared.
