recorded at about every 1.00 mL. Once the collected solution reached 25.00 mL the distillation process was stopped (Huston 38-39). The crude benzoic acid, which was placed aside in the lab before, was collected into capillary tube. The pure benzoic acid was collected within a separate capillary tube. The collected samples were then placed within a Melt Temp Apparatus. The dial was then placed on a low-medium voltage, and the capillary tubes were observed until the melting point of the crude and pure benzoic acid was reached (Huston 34-35). Results: During the distillation process the temperature of the collected solution at 1.00 mL was that of 54.3 degrees Celsius. At 2.01 mL the temperature was 54.9 degrees Celsius. In the range of 3.02 mL to 22.01 mL the temperature was that of a consistent 55.1 degrees Celsius. Then once the amount of the collected solution reached 23.02 mL the temperature raised to that of 55.3 degrees Celsius. Then at 24.00 mL and 25.01 mL of collected solution the temperature reached its’ peak of 56.0 degrees Celsius. The unknown solution C is believed to be that of Acetone which has a boiling point 56 degrees Celsius. During the Melt Temp Apparatus part of the experiment the two capillary tubes containing the crude and pure benzoic acid were observed until the melting points of the two crystal compounds were reached. The pure benzoic acid had an observed melting point range of 124.2 degrees Celsius to 125.4 degrees Celsius. The crude benzoic acid melting point consisted of a range from 125.1 degrees Celsius to 128.3 degrees Celsius.

    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.
