Why does it make a difference if you mark chromatography paper with a pencil and not with a flair or ink pen?

Because the ink from the pen will run and smear during the chromatography but the pencil mark is not affected.

∙ 12y agoa chromotagraphy is intended to split up a mixture of compounds into its subparts. if you use a pen, the ink will also be separated. that is why you use a pencil instead. Graphite (pencil lead) cannot be broken up into further components which can be separated by TLC and it is also not likely to cause reaction with any TLC components.

This will not enhance your experiment, and the writing may be illegible.

Because the ink from the pens with smear and run but if you use pencil to draw the line then it will not smear. It will stop the ink running past it aswell

Lead pencil to mark chromatography paper?
Yes, better than ink!

How is paper chromatography used in everyday life?
it can be used in everyday life by liquid chromatography, gas chromatography, thin-layer chromatographyand paper chromatography.
Why is ink never used for drawing the baseline on the chromatography paper?
Depending on the ink and the solvent used for the chromatography, the ink might also migrate and be separated into its components or smear over the paper. With the graphite of a pencil, this will not happen.

Why was a ball pen not used to draw the line?
In chemistry, a pen is not used to draw lines on chromatography paper. A pencil is used to draw lines on the paper because the ink can smear and interfere with the chromatography and the ink will dissolve in the chromatography solvent.

Why should the water be below the pencil line in chromatography?
because when we usually test for a liquid or anything soluble we put a drop of it on the pencil line, then when we put the chromatography paper or filter paper in water the water will get on the paper and start moving upwards here when the water will approach the liquid or solvent or die and then they will move with water throughout the filter or chromatography paper.
What would happen if you submerge the chromatography paper above the pencil line?
Try and see: if it wouldn't be above the level of solvent, the spots will run off.
Where may one learn about paper chromatography?
If you like science Paper Chromatography is something to look into. You can take Chemistry classes to find out different ideas on how to use Paper Chromatography.

What is grass chromatography?
There is no such thing as grass chromatography. there is only High Performance Liquid Chromatography, Gas Chomatography, and Paper Chromatography.
Are paper and thin layer chromatography types of planer chromatography?
yes.
