The basic purpose of the solvent is to move the pigments up the chromatography paper through capillary action so that the pigments can be separated. The basic importance of chromatography is to separate different solvents by their molar mass. In doing so, one can separate the different pigments within a solution and measure how much of each pigment is present.

What does it mean if the spot is in the solvent front in chromatography?
it means that the solvent dissolves the solute.
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 is the moving solvent called in chromatography?
Mobile phase.
Is methanol a good solvent to use in paper chromatography?
Because methanol is a very polar solvent
What uses electrostatic attraction to separate a solute from a solvent?
Chromatography

What is the purpose of an alumina column?
Column chromatography is generally used as a purification technique: it isolates desired compounds from a mixture.Column chromatography is separated into two categories, depending on how the solvent flows down the column. If the solvent is allowed to flow down the column by gravity, or percolation, it is called gravity column chromatography. If the solvent is forced down the column by positive air pressure, it is called flash chromatography, a "state of the art" method currently used in organic chemistry research laboratories The term "flash chromatography" was coined by Professor W. Clark Still because it can be done in a "flash."
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 is the moving solvent called in chromatography?
Mobile phase.
Is methanol a good solvent to use in paper chromatography?
Because methanol is a very polar solvent
What uses electrostatic attraction to separate a solute from a solvent?
Chromatography
What is the best solvent for phenol for use in Gas Chromatography?
water
Why the descending method of chromatography is faster than the other method?
•Descending chromatography is faster because gravity helps the solvent flow.
How is extraction related to chromatography?
Both are techniques of analytical chemistry and use a solvent.
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.
Is solvent extraction extraction a type of chromatography?
we can say this because both of these are separation technique
