What will happen if there is an overrun of solvent in paper chromatography?

The Rf value cannot be determined since the distance of the solvent may overlay in the paper.

What are the relations with pigment and chromatography?
the more soluble the plant pigment is with the chromatography solvent, the farther it will travel up the chromatography paper
Is methanol a good solvent to use in paper chromatography?
Because methanol is a very polar solvent
Is water a major component of the solvent used in paper chromatography?
The water dissolves the paper molecules.
A hypothesis for paper chromatography?
A hypothesis for paper chromatography depends on what you are making the hypothesis on. A hypothesis for the speed of chromatography could be that you think the speed of the process can be changed depending on the type of paper, or whatever the stationary phase is, and the type of solvent being used.
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 solvent is used in Paper chromatography?
In chromatography you need one stationery phase (paper) and one mobile phase (here solvent, moving by capillary forces)

A method of separating mixtures by using chromatographic paper and a solvent?
This method is called paper chromatography.
Is water a major component of the solvent used in paper chromatography?
The water dissolves the paper molecules.
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.

What is paper chromatograph?
Ascending paper chromatography is where a chromatogram rises, or ascends. The paper moves up because the solvent moves it in an upward direction.
Why stop paper chromatography from reaching the top of the paper?
The end of the paper nearest the spot is allowed to be in contact with a suitable solvent, WITHOUT immersing the spot itself. If the spots were immersed they would dissolve in the solvent and be pulled down into the solvent itself.

In chromatography why do some colours not spread up the paper?
They do not move up because the aren't soluble the solvent
