Why during chromatography must the paper NOT touch the sides

In summary, it is important for the paper to not touch the sides during chromatography because it can affect the movement and separation of the substances being analyzed. If the paper does touch the sides, it can lead to inaccurate results and make it difficult to determine the components present in the mixture. To prevent this, the paper should be cut to the appropriate size and secured properly in the chamber. This is necessary for all types of chromatography to ensure accurate results.

Homework Statement


why during chromatography must the paper NOT touch the sides of the test tubes in which the experiment is being carried out?

Homework Equations


The Attempt at a Solution


I am not sure but could our results get smudged or distroted?
if so I still can't work out how? could it be that the solvent does not run in a straight line :S

What might happen if the glass wall started wicking solvent from the chromatogram during the experiment?
 

Related to Why during chromatography must the paper NOT touch the sides

1. Why is it important for the paper to not touch the sides during chromatography?

It is important for the paper to not touch the sides during chromatography because it can affect the movement and separation of the substances being analyzed. The paper acts as a medium for the substances to travel through, and if it touches the sides, it may cause uneven movement and distort the results.

2. What happens if the paper touches the sides during chromatography?

If the paper touches the sides during chromatography, the substances being analyzed may not separate properly. This can lead to inaccurate results and make it difficult to determine the components present in the mixture.

3. Can the paper touching the sides affect the outcome of the chromatography experiment?

Yes, the paper touching the sides can definitely affect the outcome of the chromatography experiment. It can cause variations in the rate of movement and separation of the substances, leading to unreliable results.

4. How can we prevent the paper from touching the sides during chromatography?

To prevent the paper from touching the sides during chromatography, the paper should be cut to the appropriate size and placed carefully in the chamber. The paper should also be secured properly with clips or tape to ensure it stays in place during the experiment.

5. Is it necessary to keep the paper from touching the sides for all types of chromatography?

Yes, it is necessary to keep the paper from touching the sides for all types of chromatography. Whether it is paper chromatography, thin-layer chromatography, or column chromatography, the paper should not touch the sides to ensure accurate results.
