WebDMSO is a very polar, aprotic solvent. DMSO has something in common with water. Water is very polar, with a polar O-H bond. DMSO is very polar, having a strongly polarized S-O … WebPigments that are more nonpolar will dissolve better in this solvent, traveling farther up the strip. More polar pigments that have residual charges (like water) will not interact much with the solvent, staying closer to the bottom of the strip. High Rf values from TLC using a nonpolar solvent means the pigment is more nonpolar.
