The Rf values...

Question

The Rf values of A B in a mixture determined by TLC in a solvent mixture are 0.65 and 0.42 respectively. If the mixture is seperated by column chromatography using the same solvent mixture as a mobile phase, which of the components, A or B, will elute first?Explain

Open in App

Solution

Rf Value = Distance from Baseline travelled by Solute/Distance from baseline travelled by solvent

.As value of Rf is more for solute A than solute B so distance travelled by solute A will be more than travelled by solute B so A will elute first.
