To start the experiment, the melting point apparatus needed to be calibrated. In order to do this, a known compound, with a known melting point, was tested to see what temperature that compound would melt at. Depending on how distant the experimental numbers were from the expected results, the accuracy of the apparatus could be calculated. In the case of this experiment, 2-Acetonapthane was chose as the compound to calibrate the device with. 2- Acetonapthane is known to melting point range between 53 – 55 °C. For the device used, the 2- Acetonapthane melted within a temperature range of 56 – 59 °C. That meant that the melting

    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.

    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.
