1 If dye A is organic in nature then it will be more soluble in nonpolar isopropanol than any polar solvent So it will migrate larger distance in solvent with more isopropanol 2 TLC can be used to help identify unknown compounds Explain how this might be accomplished using the dyes as an example TLC or thin layer chromatography has a thin layer of solid adsorbent like SiO2silica or alumina Al2O3 applied on glass or plasticcalled the stationary phaseA solvent generally nonpolar is allowed to flow through the stationary phasethe mobile phase carrying the components of the mixture with itMostly non polar components of the mixture is separated by the nonpolar mobile phase and the polar    See Answer
