1 of 5
Why do we use pencil instead of pen for the baseline on the filter paper?
because the ink will be separated by the chromatography solvent.
2 of 5
Why do we make sure to baseline is kept above the solvent?
So the baseline is not carried up the filter paper along with the dye/colouring.
3 of 5
Why do we put on a lid during this experiment?
to prevent evaporation
4 of 5
You can use known samples alongside an unknown sample to identify the dyes that the unknown sample contains. True or False?
