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 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 Rf value of methyl orange?
5
What is Rf value of o-nitroaniline?
The Rf value will vary some depending on the exact conditions. Using a silica plate and a moderately polar solvent (dichloromethane or a mixture of toluene/ethyl acetate) you will get an Rf of 0.4-0.5.
What are the maximum capabilities of an RF Cable?
An RF cable is an electrical connector designed to work at radio frequencies in the multi-megahertz range. Breakdown is a function of maximum voltage. Maximum capabilities is dependent on frequency since the typical value of VSWR is proportional to the increase in frequency.
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 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 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
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 minimum value of Rf?
Zero
