Paper Chromatography

Question 1

Describe this technique (paper chromatography) is carried out
(4)

Answer 1

A small amount of the mixture to be studied is placee on a strip of adsorbent paper e.g. filter paper

End of paper is placed in a suitable solvent

The solvent soaks up through the paper and dissolves the sample of material being analysed

As the solvent (mobile phase) moves up through the paper (stationary phase) each of the components of the mixture is adsorbed to a different effect on the paper

Question 2

What is the mobile phase in this technique?

Answer 2

The solvent

Question 3

What is the stationary phase in this technique?

Answer 3

Filter paper

Question 4

Give an example of adsorbent paper?

Answer 4

Filter paper or chromatography paper

Question 5

Filter paper and chromatography paper are examples of what?

Answer 5

Adsorbent paper

Question 6

Explain what the end result is

Answer 6

The original sample separates out into it’s various components at different intervals along the paper
