Gary Lam Experiment #1: Investigating Solubility and Acid-Base Reactions Purpose: The purpose of this experiment is to understand the solubility of compounds and how acid-base properties affect solubility. Results: See attached pages for tables regarding the results of the experiment. Discussion: In part 1, diethyl ether is relatively non-polar and miscible with hexane, which is also non-polar. Dichloromethane is polar, but non-polar enough to mix with hexane. Ethanol, ethyl acetate, and water are all polar which makes them immiscible with hexane. With acetone, there should be layering because it is polar and hexane is non- polar but our experimental data said the resulting solution was fully miscible. This error could have been caused by observing the solution incorrectly. In part 2, diethyl ether and toluene are relatively non-polar which makes them immiscible with polar water. Dichloromethane is polar but not polar enough to mix with water. Acetone and ethane are polar, which makes them miscible with water. With ethyl

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
