The answer is: molecular polarity.
Paper chromatography is an analytical method used to separate colored substances.
Substances are distributed between a stationary phase and a mobile phase.
Substances have different chemical structures and because of that, the different polarity, so each molecule have a different solubility in the solvent.
If a substance is very nonpolar, it will not dissolve at all in a very polar solvent.
If water (polar substance) is a solvent, the more polar the color, the higher it will rise on the papers.
FeS known as iron sulphide is formed by the following reaction:
Fe + S ................><span> FeS
</span>
Iron sulphide has a molar mass of 87.910 grams. It has a grey color and can either be in the form of a powder of in the form of lumps.
It is insoluble in water and it reacts with acids.
Its density is 4.84 g/cm^3 and it has a melting point of 1194 degrees celcius.
