Lab Report #1: Investigating Solubility and Acid-Base Reactions Purpose: The purpose is to understand the solubility of polar and non-polar solutions and how acid-base properties affect this solubility. Discussions: In part 1, diethyl ether is miscible with hexane and is therefore non-polar. This is because hexane is a non-polar solvent. The rest of our results show that ethyl acetate, acetone, ethanol, and dichloromethane are miscible as well. However, all of these solutes are polar and should have been immiscible and formed layers. Dichloromethane is an exception since it is non-polar enough to mix with hexane and become miscible. It’s possible that the solutions were not observed properly or not enough solute was added. The resulting solution of hexane and water formed white precipitate and is therefore immiscible (4B). In part 2, ethyl acetate, acetone, and ethanol are polar solutes, so they should be miscible with water and create a clear solution. However, our results show that ethyl acetate formed a clear layer on top making it immiscible (5T). Again, this error could be due to improper observation or lack of mixing the solution. Diethyl ether and toluene are non-polar, so they
