Chemistry 2510 Introduction to Experimental Organic Chemistry Spring 2009 Experiment #1 Recrystallization and Melting Points Laboratory Notebook : You need to summarize your experimental plan in your lab notebook. Be sure to include a table of all reagents and compounds that will be used in this experiment, including safety hazards, physical constants, and other important properties for each. Laboratory Observations: Be sure to record any observations during the laboratory. You must record exactly how much of the starting materials you started with and the weight of the isolated product. You will also want to note the color, shape, and general appearance of the crystals from both methods that you attempt. Results and Conclusions : Calculate a % recovery for all methods of recrystallization. You will also determine the melting points for crystals obtained from both methods. Compare your results and observations to other students in your lab that have used other methods.

    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.
