Chromatography

  Hey everyone welcome back today in Science we were learning about Chromatography. I hope you enjoy my blog have a wonderful day Good-Bye


What is Chromatography?
It is the process of separating a mixture based on the pigments 


What are pigments?
  They are a substance that gives colour to things. They are used to give colour to all sorts of things like felts, paints, plastic, food ect. In other words they are particle  


Experiment 

Our aim of the experiment is to separate the different pigments from ink using chromatography 


Hypothesis: 
I think that they will separate and it will change colours 


Method:

1. Draw a line across the filter paper in pencil, 5cm from the bottom

2. Draw a coloured dot in the center 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/DOT IS NOT IN THE WATER 

5. wait 5 minutes and observe the results.


Equipment:

Felt tip pen, filter paper strips, test tube, measuring cylinder, pencil, 


Observed and discussion 

When we did the experiment the colour moved up and it looked very cool i couldnt get a photo of it sorry
