The migration is dependent on affinities and hydrogen bonding. Solute concentration does not change the migration of individual components in the sample. Nonpolar molecules will not be attracted to the water molecules attached to the cellulose and will travel further along the paper, while polar molecules will have a high attraction for the molecules and not travel as far Hydrogen bonding to the stationary phase will determine the migration of individual components in the sample. Nonpolar molecules will not be attracted to the water molecules attached to the cellulose and will travel further along the paper, while polar molecules will have a high attraction for the molecules and not travel as far. We’re told in our question stem, water absorbed on cellulose (a very polar compound) functions as the stationary phase. The higher the adsorption to the stationary phase, the slower the molecule will move through the column. All chromatography works by having a mobile phase (the part that moves), and a stationary phase (the part that stays still) which allow for separation of the different fractions of the original mixture. Chromatography is a separation technique that takes advantage of the different products’ solubilities and relative affinities for the stationary phase used. To answer this question, we can do a quick overview of chromatography, then we’ll identify the principal factor determining the migration of individual components in the sample. 1) Despite being a passage-based question, we should be able to answer this question using external knowledge.
