leave until is close to the top of the paper.
(i) Describe how the student should complete the experiment after placing the four spots on the paper.
Suggest why food colouring F did not move during the experiment.
How many food dyes are there in food colouring E?
How many known food dyes are there in food colouring H?
Record the results for the dye in G and calculate its Rf value. Give your answer to 2 decimal places.
Tick the colour(s) that include a dye that is not safe
Identify the unsafe dyes
Explain how the different dyes in X are separated by paper chromatography.
The soluble the dye is in the moving
and the the dye is attracted to the solvent adsorbed on to the chromatography
The the dye moves in the same time
