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.
Blue.
The largest Rf value is 1, which occurs when the compound remains at the origin of the chromatogram and does not move at all. The smallest Rf value is 0, which happens when the compound moves with the solvent front and does not adhere to the stationary phase.
If the absolute value of the negative is bigger than that of the positive, then the answer is negative. If the absolute value of the negative is the same, then zero. If the absolute value of the negative is smaller, then positive. Absolute value is the value ignoring the sign.
The result will be a negative value.
Rf is about .45
It will depend on the solvent system you are using.
The Rf value depends on the type of plate used and solvents.
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
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
1, if it completely solube in the solvent, it will travel with it, right to the solvent front.
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
anthocyanins rf vlaue is o.95
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 Rf value value is 8.44 as the particles are lighter than the solvent
As a general rule the longer the carbon chain the greater the Rf value.
about 0.342
