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
Will acetaminophen or ibuprofen have a higher Rf if you carry out a TLC separation of on a silica gel using a non-polar developing solvent?
Acetaminophen will have Rf value of about 0.4 and ibuprofen will have Rf value of about 0.6 if the non polar solvent used is ethanol.
What is the rf value of cocaine?
Rf is about .45
Why does carotene have the highest Rf value?
The Rf value of the xanthophyll is two thirds that of carotene because xanthophyll has an H bond with cellulose, which slows it down, and makes it less soluble in the solvent. Carotene is more soluble in 9:1 petroleum-ether acetone solution, which caused it to be carried higher and have a larger Rf value.
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
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 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.
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 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 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
