Saturation affects the RF value in a significant manner. With saturation of the air, this will result into high RF value which cause poor resolution.Ê
The maximum RF value that can be obtained is 1.0. This means that the substance travels the full distance of the chromatography medium being used. Any RF value greater than 1 is not physically possible.
The RF value of benzoic acid in ethyl acetate is 0.68.
The Rf values do not indicate the solubility of a substance. The Rf value or retardation factor is the ratio of the distance traveled by the center of a pot to the distance traveled by the solvent front in chromatography.
A combination of a nonpolar solute and a polar solvent will result in the largest RF value.
The Rf value of methyl orange depends on the solvent and the stationary phase used in the chromatography experiment. However, in a common solvent system like 50:50 water:ethanol, the Rf value of methyl orange is around 0.75.

Rf is about .45
It will depend on the solvent system you are using.
the mobility of any component in a particular solvent is referred to as its RF value. Mathematically, RF value = distance travelled by solute/ distance travelled by the solvent
The rf value is shorthand for the retention value of a substance. It is used in chromatography to determine the components of an unknown sample.
The maximum RF value that can be obtained is 1.0. This means that the substance travels the full distance of the chromatography medium being used. Any RF value greater than 1 is not physically possible.
The RF value of benzoic acid in ethyl acetate is 0.68.
the Rf value value is 8.44 as the particles are lighter than the solvent
The Rf values do not indicate the solubility of a substance. The Rf value or retardation factor is the ratio of the distance traveled by the center of a pot to the distance traveled by the solvent front in chromatography.
As a general rule the longer the carbon chain the greater the Rf value.
