Flashcards

Paper Chromatography

The technique of separating substances using their different solubilities in a solvent and a stationary phase.

Solubility

The ability of a substance to dissolve in another substance.

Solvent

The substance that moves up the paper in paper chromatography, carrying the components of the mixture.

Origin Line

The line on the paper where the mixture is initially applied, before the solvent starts moving up.

Pigment Travel Distance

The distance a pigment travels on the paper depends on its solubility in the solvent and the paper. The more soluble it is in the solvent, the further it travels.

Study Notes

Paper Chromatography

Paper chromatography uses the different solubilities of substances to separate them.
This technique is used to isolate and identify various pigments in inks and dyes.
The process involves a solvent moving up paper, dissolving pigments at the starting point.
Pigment movement speed depends on solubility preferences.
Pigments more soluble in the paper move slower.
Pigments more soluble in the solvent move faster.
The distance a pigment travels indicates its solubility in both media.
