Rf is about .45
It will depend on the solvent system you are using.
The Rf value of a substance is a measure of its migration distance during chromatography. A substance with an Rf value of 0.803 would mean that it traveled 80.3% of the total distance from the origin to the solvent front during the chromatography process. The specific identity of the substance would depend on the experimental conditions and the properties of the compound.
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 for 4-aminophenol is the distance traveled by the compound divided by the distance traveled by the solvent front. The Rf value can vary depending on the specific solvent system and conditions used in the chromatography experiment.
The Rf value would not be the same for every solvent as there are factors that allow each solvent to be unique. The attractive force, particle size and solubility of each solvent will create different results each time.

If you switch from a hexane-ethyl acetate solvent system to ethyl acetate only, you would expect the Rf values to decrease. Ethyl acetate is a more polar solvent than hexane, so compounds will interact more with the solvent and have shorter distances of travel on the TLC plate, resulting in lower Rf values.
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.
Replacing ammonia with acetic acid may affect the polarity of the solvent system, potentially leading to changes in the separation and resolution of compounds in the mixture. The Rf value could be different for codeine or other components due to the altered interaction between the solvent, compounds, and the stationary phase. This change could impact the accuracy of identification or quantification of codeine in the tablet mixture.
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 of benzoic acid in ethyl acetate is 0.68.
the Rf value value is 8.44 as the particles are lighter than the solvent
