That depends on many factors including the elution solvent used, the type of TLC plate used, etc.. When using .5% of acetic acid in ethyl acetate as your elution solvent and on a plastic backed plate, the Rf-value should be around 79.82%
0.6
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.
In general, as saturation increases, the RF value decreases. This is because an increase in saturation tends to increase retention of the compound on the stationary phase, resulting in a lower RF value. Conversely, lower saturation levels may allow the compound to move more freely, leading to a higher RF value.
the Rf value value is 8.44 as the particles are lighter than the solvent
The Rf value indicates the ratio of the distance a pigment travels compared to the distance the solvent travels on a chromatography plate. The higher the Rf value, the more soluble the pigment is in the solvent used for the chromatography.
As a general rule the longer the carbon chain the greater the Rf value.
The Rf value of eugenol is around 0.61-0.63, when using a suitable solvent system like ethyl acetate:benzene (7:3).
The RF (retention factor) value for aspirin on a TLC plate is typically around 0.4-0.5. This value is calculated by dividing the distance traveled by the compound by the distance traveled by the solvent front. It is a useful parameter for identifying and characterizing compounds on a TLC plate.
the rf value equals the distance of the component from the starting point divided by the distance of the solvent from the starting point.
