Partition (or Distribution) Coefficient I best way to think about this is to start with a solute that is not in solution, then add a mixture (Not a homogeneous mixture! Why?) of water (or aqueous acid or base) and an organic solvent (such as diethyl ether). Swirl the solute with the solvent mixture until everything is dissolved. Then let it stand, because two immiscible solvents where used, you will have two layers. (Question: Which solvent will be on top, which on the bottom?

. Consider the two molecules shown here. 1-butanol (1)- 7.3g/100ml and butyric acid (2)- miscible The solubilities of each in water is given. What is “solubility”? What does the solubility value given for (1) here mean? Please explain, based on their structures, why the solubility of (2) is greater than the solubility of (1) in water. For a complete answer, you should start with the types of IMFs involved in the different parts of the dissolving process. You should also use the kind of reasoning from class regarding the contributions…
