Annika Gacnik GSI Anderson Lo Experiment 2: Investigating Solubility and Acid-Base Reactions Part I: Hexane is a non-polar molecule, and thus dissolves diethyl ether, ethyl acetate, acetone, ethanol, and dichloromethane because they are also non-polar molecules. The intermolecular forces present in these interactions are Dipole-Induced Dipole and Induced Dipole-Induced Dipole. Hexane does not dissolve water because water is polar and its hydrogen bonding keeps it from bonding with hexane. Part II: Ethyl acetate, acetone, dichloromethane, and toluene do not mix with water because they are all non-polar and incapable of hydrogen bonding. Ethanol is miscible in water because it is capable of hydrogen bonding with water. Diethyl ether should be partly miscible in water because its slightly negative oxygen can bond with water’s hydrogen, however our results did not show that the two were miscible. Part III: The ethanol formed two layers after adding only 5 drops, although it should have dissolved infinitely because it is capable of hydrogen bonding with water. 1- Propanol also should have been immiscible indefinitely because of its ability to form hydrogen bonds with water, but our results showed that it became immiscible after
