In this video you will learn all the science for this topic to get a grade 9 or A* in your science exams! In this video, you will learn this model answer to.
How To Calculate Rf Values
What is R F Value? The R f (retardation factor) value is the ratio of the solute's distance travelled to the solvent's distance travelled. The word comes from chromatography when it was discovered that a given component will always travel the same distance in a given solvent under the same conditions.
Calculating Rf (Paper Chromatography) GCSE Chemistry Revision YouTube
Retardation or retention factor (Rf) value is the ratio of distance traveled by the analyte to that of the solvent front on a chromatogram. The chromatographic techniques in which the analytes are added to the stationary phases show a difference in the movement of analytes with mobile solvents (phases).
Explaining how to calculate Rf values YouTube
Formula The formula for calculating the RF Value is straightforward: RF Value = Distance Traveled by Solute (DSU) / Distance Traveled by Solvent (DSV) Distance Traveled by Solute (DSU) represents the distance the solute travels from its origin on the chromatographic medium.

In thin-layer chromatography, the retention factor (Rf) is used to compare and help identify compounds. The Rf value of a compound is equal to the distance traveled by the compound divided by the distance traveled by the solvent front (both measured from the origin).

The Rf value would be (8 - 4) / 15 = 0.27. FAQs: What is the significance of Rf values in chromatography? Rf values help in identifying and comparing substances based on their movement on a chromatogram. Can Rf values be greater than 1? Yes, in some cases, Rf values can exceed 1, indicating that the substance traveled farther than the solvent.
