rf factor and chromatography

What is the paper chromatography?

Technology that is used for seperation and identification of mixtures

What are the four factors that affect the rate of movement of a solution during chromatography ?

Solubility, molecular size and weight, polarity and adhesion of the compound with paper.

The more soluble

The farther it will go

The heavier the size and weight of the molecule

They less it will move

The more similar the polarities of the solution

The closer it will get

The more adhesive the solution is

The less it travels

What is RF factor ?

A method used to quantify data from chromatography

The formula for rf factor is ?

Rf = distance traveled by compound/distance traveled by solvent (solvent line)

The Rf factor is always

Between 0-1

The closer to one the rf factor is means that it traveled _______

Far

There are always two lines for one pigment while doing RF factor problems. Only measure the _______ line

Top or front
