Why wait 75 minutes for paper chromatography?
We need to wait for 75 minutes for the component and solvent to move a maximum distance...
What is propelling force in paper chromatography?
The force act to shift the component of the mixture from their point of origin and displaces them in the direction of solvent flow.
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
What is a suitable solvent for paper chromatography?
In paper chromatography n-butanol:acetic acid:water mixture in the ratio 4:1:1 is used as a solvent whereas in case of thin layer chromatography(TLC) petroleum ether and acetone in the ratio 9:1 is used as a solvent. Also, in some cases, DCM(dichloromethane is used as a solvent.

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)
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

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.

A method of separating mixtures by using chromatographic paper and a solvent?
This method is called paper chromatography.
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.
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.
