Question

After doing an experiment, a chemist determines the Rf value of a compound to be 4. He also notes that the solvent travelled 4 cm on the plate. What can you conclude about this experiment

Answer 1

We can conclude that the Rf of that compound has a ratio of 4. It means that the solute has a ratio value of 4 times than that of solvent. As we can see that it has traveled 4 cm , this data is useful in determination of the compound in a mixture when compared with Rf values of other compounds.
