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
Does polarity of a solvent mixture affect the completeness of the separation in chromatography?
you just talk to spongebob and it will make sense. He's spongey.
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 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.
Some components of ink are minimally attracted to the stationary phase and very soluble in the solvent Where are these components located on the filter paper during chromatography?
I hate when people ask questions and there is no answer. I need to complete my chemistry homework!

Why is the mixture placed above the level of the solvent in chromatography?
If not, the mixture would just soak out into the liquid in the tank.
In chromatography why do some colours not spread up the paper?
They do not move up because the aren't soluble the solvent
Mobile phase in relation to chromatography?
a moving or mobile phase is a mixture you want to separate , dissolved in a solvent.
What solvent is used to separate a mixture of sulphur and carbon?
Sulfur is soluble in carbon disulfide.
What solvent can be used for food colorings when doing paper chromatography?
Water should work well as food colourings are usually water soluble.

What is the extract?
The partial removal of a substance from a solution or mixture by dissolving in another,immiscible solvent in which it is more soluble

Why is water not the best solvent to use in paper chromatography?
acetone or butanol That totally depends on the solute you are trying to separate. Methylene Chloride generally works much better as an all around solvent due to its mild polarity and organic functional groups. Acetone won't work at all if you have 2 polar solutes. They will travel with the solvent front and not separate at all! In other words, it depends on your solute. Cheers, Ty
What is s soluble?
A substance which can dissolve in a solvent is said to be soluble in that solvent
