---In-Lab-[Part 2a]-- (20pts) A. Actual Procedure and Observations This is an account of what really was done. Do not regurgitate the laboratory manual. You need to write the procedure as it was exactly carried out. If the procedure has been modified or changed in any way from the original experiment, note the changes here. Remember that the procedure section should be sufficiently detailed, such that another student would be able to repeat the whole experiment based on your report. Keep the following points in mind: (i) Use the third person, the passive voice, and the past tense. In this case, you have just performed it, so you need to use passive voice and past tense. Correct: The solution was heated on a hot-plate for 30 minutes. Incorrect: I heated the solution on a hot-plate for 30 minutes. Incorrect: The solution is heated on a hot plate for 30 minutes. (ii) Avoid the “recipe format”. Recipes are written in a command tense, telling you to do something. This is not the way you should be writing your observations. Incorrect: Heat the solution on a hot-plate for 30 minutes. (iii) Incorporate your observations into the procedure. (ex) The solution was heated on a hot-plate for 30 minutes during which time the color of the solution changed from red to green. (iv) Observations should be concisely written. Avoid unnecessary detail. (ex) The reaction mixture turned green and a precipitate formed. The precipitate was collected using a Buchner funnel and washed with water. The crude product, in the form of yellow crystals, had a mass of 15.0 mg. ---Post-Lab-[Part 2b]-- (50pts) A. Results: This is one of the most important sections of your report. Whenever possible, tabulate your data, such as the melting/boiling point with its range. Analyze the IR and/or NMR spectra, and any other observations or measurements. Include all the spectra, which will be provided on the course website, with your interpretations and peak assignments. Show clearly how you performed any calculations. B. Discussion: This is the most important section of your report. This section should be completely based on your results (measured or calculated values) and observations. The values you recorded are your data and you need to consider the meaning of your data. You also need to show your understanding of the experiment. The discussion is written in the passive voice and past tense just like your observations. Sometimes you will need to cite references where you obtained any supplementary information. Tips for writing a good discussion: First, your discussion should state what you've made and what it appears like. Was it as expected compared to the literature? e.g. white shiny crystalline solid. Next, discuss the yield and purity of the product(s) you recovered/synthesized. Qualitatively assess the performance. A discussion should quote actual experimental values and not talk in vague terms.

    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.
