1 October 2008 Lab #2 Discussion The purpose of this lab was to explore how acid-base properties affect solubility through a series of tests, which will be discussed in separate sections for organizational clarity. Part 1 explored the miscibility of solutes with a non-polar solvent, hexane, by mixing the two components and observing the results. Diethyl ether, ethyl acetate, acetone, and dichloromethane all dissolved, because they are non-polar solutes whose main intermolecular interactions with hexane consisted of dipoles. Water formed a separate layer due to its polarity. Part 2 followed the procedures of Part 1, but with a polar solvent, water. All the solutes formed a separate layer above the water, because the water’s polarity repelled the non-polar intermolecular forces of the solutes. Part 3 was very similar to Part 2, but used various alcohols as solvents. The alcohols that contained more than 3 carbon groups did not dissolve in water. 1-propanol and 1-ethanol, in contrast, could be added until the solution reached saturation, because the induced dipole-induced dipole
