What is the rf value of cocaine?
Rf is about .45
What is the Rf value of salicylamide?
It will depend on the solvent system you are using.
What is rf value and how is determine?
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
What is the RF value for 4-aminophenol?
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.
What is Rf-value Why its has no unit?
There are no units because it is simply a ratio

What is an rf value used for?
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.
What is the maximum and RF value can be?
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.
How does saturation effect RF value?
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.
What is the RF value of benzoic acid in ethyl acetate?
The RF value of benzoic acid in ethyl acetate is 0.68.
What is the RF value for red ink blue ink and green ink?
the Rf value value is 8.44 as the particles are lighter than the solvent
What do the Rf values indicate about the relative solubility of the pigment in the 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.
What is the relationship between chain length and Rf value?
As a general rule the longer the carbon chain the greater the Rf value.
What is the Rf value of phenacetin?
about 0.342
What is the minimum value of Rf?
Zero
