Experiment 2: Solubility The purpose of this experiment is to gain good comprehension of solubility behavior to understand the experiments performed in the future in an organic chemistry laboratory. In Part A, the solubility of solids benzophenone, succinic acid, and biphenyl are tested by combining them with solvents water, methyl alcohol, and hexane. When combining Benzophenone and H 2 O, the Benzophenone was insoluble and showed hydrophobic characteristics when mixed vigorously. When combining the Benzophenone and methyl alcohol, benzophenone was soluble in methyl alcohol. When mixed together, the benzophenone seemed to clump together near the edges of the test tube but as time passed, the acid completely dissolved in the methyl alcohol. And, when Benzophenone and hexane were combined, the solution was insoluble even after 60 seconds of vigorous shaking. The second acid, Succinic Acid, when combined with water was 80% soluble (partially soluble). The solution became very cloudy after 15 seconds of shaking, and become more than 50% soluble after 25 seconds. When succinic acid was added into methanol, it became soluble after 45 seconds of vigorous mixing. This reaction occurred more rapidly than the other reactions performed previously. And when succinic acid was added to hexane, it was completely insoluble. No acid was dissolved in hexane. The third acid, Biphenyl, when combined with water was insoluble. When biphenyl was added to water, it showed hydrophobic characteristics. When biphenyl was added to methanol, it was partially soluble (around 75%). This reaction occurred very slowly compared to the other reactions performed. And lastly, when biphenyl was added to hexane, it was soluble. This reaction occurred quite rapidly, as more than 50% of the soluble had dissolved at 20 seconds and all the acid was dissolved at 35 seconds. The data table below sums up all these results.

In Part B, the experiment tested the solubility of different alcohols: 1-Octanol, 1-Butanol, and Methanol when mixed in solvents: Water and Hexane. When 1-Octanol when added to H 2 O, it was insoluble. After 6 drops of 1-Octanol combined with water, the reaction takes place and forms two visible

    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.
