Chromatography is a physical separation method in which the components of a combination are separated by difference in their distribution between two phases, one of which is stationary and the other is mobile, moving in a definite direction.
The results are due to the different solubilities of every substance. More soluble substances would travel faster on the chromatography paper.
Rf value=Distance moved by substance/Distance moved by the solvent
Same dyes/substances will have the same Rf value under identical conditions, which is how substances can be identified through their Rf values.
I was absent on the day, so I borrowed data from my friend:
2.9/9.9= 0.292(to 3sf)
