What are the two properties of the ink components that determine their movement along the chromatography paper/fabric (see Introduction)?

The two properties of the ink components that determine their movement along the chromatography paper/fabric are:

the solubility of ink constituent in chemical solvent.

the mixture of colour constituents in the ink.

Explanation:

Chromatography is the process in which the chemicals of the mixture are separated on the basis of constituents.

Capillary action let the colors of ink separate into their constituents. When ink is subjected to solvents it gets dissolve and gets separated.

The property of ink that led to determine their movement is:

Ink is made of many dyes of different colours, pigments etc.

The chemicals that has the best solubility in the chemical will move up on the chromatography paper and fabric.

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.
