Abstract: The objective of this lab was to determine the melting points of three unknown compounds using Digi-Melt (Mel-Temp) electronic apparatus to obtain melting point ranges close to the accepted value. This lab was also done to identify the three unknown compounds based on their melting point range. The experimental plan for this experiment was conducted by collecting three of the four unknown compounds that were given to find their melting point range. Each of the three compounds was placed into a test tube and the three test tubes were placed into the apparatus for observation. As observation continued, the temperature ranges were recorded as the compound melted from a solid phase to a liquid phase. As a result of completing this lab, each of the three compounds was identified. Compound A was found to be 1-Naphthol with a range of 93°C- 96.9°C. Compound C was found to be benzoic acid with a range of 122°C-123.7°C. Lastly, Compound D was found to be succinic acid with a range of 185.5°C-187.5°C.

    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.
