The First thing we did for this science experiment we needed to get the safety gear needed ( which was really nothing) I thought that the whole paper would turn the colour.
Scientist use chromatography to take away the colour from somethings
some of the things that we used were Ethanol, Acetone and C.solvent
First we got a little test thing then we picked our chemicals the first one we picked was the acetone it did not do much it just spread the colour
Ethanol spread the yellow just a little bit.
The reason the chemicals changed the paper to spread the colour was because of the chemicals and acid spread the colours well at least I think that is why.
