Abstract: The purpose of this experiment was to determine the solubility of different solutes in certain solvents, to determine whether the mixtures were miscible or immiscible, to crystallize impure sulfanilamide using 95% ethyl alcohol as the solvent, and to determine the melting point of the pure sulfanilamide. In the Part 2A: Solubility of Solid Compounds experiment, approximately . 040 g benzophenone was placed in four dry, labeled test tubes. Then 1 ml water was added to the first, 1 ml methyl alcohol to the second, 1 ml hexane to the third, and the fourth test tube served as the “control.” The first two test tubes were found to be insoluble, while the third was soluble. The experiment was repeated using malonic acid and biphenyl, keeping the solvents constant. For malonic acid, the first test tube was found to be partially soluble, the second was found to be soluble, and the third was found to be insoluble. For biphenyl, both the first and second test tubes were found to be insoluble, while the third was found to be soluble. In the Part 2C:Miscible or Immiscible Pairs experiment, pairs of already prepared compounds were placed in five separate test tubes, with each test tube containing a different pair. Both the water / ethyl alcohol and hexane/ methylene

    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.
