Rainbow paper Chromatography..

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 the you need:

1. Filter Paper

2. Container

3. Felts

4. Liquid

5. Ruler

6. Pencil

Process:

Step 1: You have get one filter paper the thinner version of you normal filter paper so water can soak faster through it.

Step 2: Rule two lines on the paper with a pencil. You have to put it vertically and at the top draw a line 2 cm apart from the top of the paper and at the bottom draw a 1 cm line apart from the bottom of the paper.

Step 3: Get some felts and they have to be water based felts make sure you get three felts of any colour of your choice but ideal is black, red and green so you can get a surprising reaction.

Step 4: On the paper put 3 different colour dots with you water based felts on the bottom 1 cm line, it can be in any order of colour you want also for best result make the dots big but not to big.

Step 5: Fold the 2 cm paper line making a flap you can fold it any side you want since the colour can go through both sides.

Step 6: Grab a container or in other words a cup and hang your  paper making sure the longer side is facing the inside of the cup. - Make sure the paper is just above the bottom of the cup.

Step 7: Pour such a little amount of liquid or water into the container/cup making sure the top of the water is touching only the end of the Filter paper.

Step 8: When you’ve done putting the water at the end of the Filter paper, wait and see the reaction.

I haven’t done this experiment because I was in the other class when they’re doing this experiment but my friend told me what happened so this is what the experiment is about.

  They we’re learning about rainbow paper and what colours were they using, they said that the colour that they used is really got them confused but they said is only just at the start of their experiment but after the result of they’re experiment, the thing that Mr palmer and Whaea Jo  started to get what they were talking about. They used the colours black, red and green they are just ordinary colour but when they added the water and they said that filter paper started to soak up the liquid and get to the colour. Vase on their experiment the colours started to change the black turned into a rainbow the the red turned into pink and the green turned into a yellow and colour of the blue was cool. They said that while the colours was soaking higher more colours started to appear and the colours also spread up with the water although the bottom of black and green disappeared and was only at the top. I really want to this activity because it looks like it was really fun and  my friend said they would really recommend trying this at home and have fun doing it.
