For this, firstly we cut up strips of chromatography paper then went and ruled a 2cm line from the bottom, then got waterbased markers and drew a big dot at the top of the line.
Then we got a beaker filled with meths/water, then folded the paper onto a pen that could go over the beaker without falling in, then placed the pen over the beaker and the water should be at least 2cm so it can just reach the line, then the water will dissolve and go up the paper causing the ink from the pen to spread making these pretty colours.
What is chromatography?
When you separate the colour from the substance.
Chroma means colour in Greek, and graph means picture/photograph
Below are two photos of the chromatography we have done!
Hey Mikayla,
ReplyDeleteThis is a fantastic read! I really like your description of what you did, I found it helpful. Unfortunately your photos aren't showing up? It would be great to see what your results were - Do you think you could add them and then comment back?
Look forward to hearing from you,
