Which samples were pure and which were mixtures?

How many different component compounds are in each mixture and what colour are they?

Are there two different coloured ink samples that contain a common component?

( ALL THESE QUESTIONS ARE RELATED TO THE COLOUR CHROMOTAGRAPHY EXPERIMENT)

i think if the colour didnt change then its pure, and if colours changed a lot then its mixture.. im not sure though. You will have to wait for drbob
Tutors here are not clairvoyant. I have no idea what you are doing other than that it is a chromatography experiment
DrBob, you missed this class.
