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 the RF value for aspirin using TLC?
Rf value changes with every experiences..... it depends on what was your solvant, the room température, the chromatograph you used..... that's why you wont find Rf tables in organic chemistry books
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 of anthocyanin?
anthocyanins rf vlaue is o.95
What is the maximum and RF value can be?
1, if it completely solube in the solvent, it will travel with it, right to the solvent front.
Which component has Rf value of 1?
Blue.
What does it mean when the Rf value is less then 0?
When the Rf value is zero, it generally refers to the position of the substance in the chromatogram. This means it did not move of that origin point.
What is the rf value of cocaine?
Rf is about .45
What does a large Rf value mean?
it indicates that the pigments were adsorbed strongly
What is the Rf value of salicylamide?
It will depend on the solvent system you are using.
What is rf value of eugenol?
The Rf value depends on the type of plate used and solvents.
How does saturation effect RF value?
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
Why are Rf values always less than 1?
Rf values are distance of substance from origin divided by distance of solvent front from origin. As the substance travels with the solvent, the solvent will always have a greater or equal value to the distance travelled by substance. This means the highest value of Rf is 1.

Is it possible to have a Rf value greater than 1?
No, it's not possible to have an RF value greater than one. Rf values are a ratio of the distance a spot has traveled to the total distance of the solvent front. Since the distance of the front is always greater than the distance of a spot, the Rf value is always less than 1.
