Question

Is the paper chromatography used normal or reverse?. Explain why

Louie performed paper chromatography to identify which among the four available reference mixtures – WAR, OFF, YIN, MEW – have the same components as his unknown sample, GUN. He spotted the standards and the sample in a Whatman No. 1 filter paper, which he placed in a developing chamber containing 3% KCI. After 20 minutes, Louie obtained the chromatogram below, immediately noting that the distance travelled by the solvent from the origin is 79.0 mm. On the other hand, the distances (in cm) traveled by the developed spots were tabulated as follows.
