Solvation is also called dissolution, and its the process of attraction between the molecules of a solvent and the molecules of a solute. Solubility is the amount of solute that can dissolve or dissociate a solvent. The process of chromatography is the figuring out the polarity of a substance by seeing how well it sticks to paper. Intermolecular forces are defined as the attraction of forces that molecules from different compounds feel based on their dipole moments (the polarity of the molecules). Intermolecular forces affect solvation because if the molecules have strong intermolecular forces, they don't solvate as easily as molecules with weak intermolecular forces. Cohesion forces are intermolecular forces that tend to resist breaking apart. A good example of cohesion forces would be hydrogen bonding because hydrogen bonding is a strong intermolecular force. Adhesion forces are intramolecular forces, which is the attraction between two different molecules. The term "like dissolves like" is employed to show that if a substance is polar, it is more likely to solvate in a polar solvent than a nonpolar solvent, and vice versa. This explains chromatography results by showing that the ink or dye will stick to the paper very effectively if it has the same polarity as the paper. If the dye doesn't have the same polarity, it will not be as cohesive.
