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
Is methanol a good solvent to use in paper chromatography?
Because methanol is a very polar solvent
What is the difference between the stationary phase and the mobile phase in chromatography?
stationary phase stays at the bottom of the paper chromatography while mobile phase is moving on the stationary phase and move on stationary phase till it gets its right place on the top of the paper or somwhere else.
What uses electrostatic attraction to separate a solute from a solvent?
Chromatography
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 descending paper chromatography?
ascending chromatography is a type of chromatography in which chromatic substance is in mobile phase and moving from bottom to top. similarly in descending chromatography mobile phase moving from top to bottom.
Mobile phase in relation to chromatography?
a moving or mobile phase is a mixture you want to separate , dissolved in a solvent.
A method of separating mixtures by using chromatographic paper and a solvent?
This method is called paper 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."

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.
