The more soluble the pigments are the faster they will move through the paper. Paper chromatography is most commonly used to separate pigments, dyes and inks.

Which pigment travels the farthest in chromatography?

WebChromatography is a separation technique used to separate soluble mixtures. In column chromatography, a mixture is dissolved in a solvent and poured down a column packed with a solid material. ... They'll move more slowly down the column and give higher retention times. ... Such substances are more soluble in the solvent and give faster ... WebThe solvent moves up the paper and over the solutes. The individual solutes will be partitioned between the stationary and mobile phases according to their relative solubility in each phase. The more soluble the solute in the nonpolar, organic, mobile phase, the farther it will move. What determines the distance the solute travels? rcm popular selection list
