POST-LAB QUESTIONS: 1. Give two physical properties you observed in your crude (unpurified) aspirin sample. 2. If the theoretical yield of a reaction was calculated to be 3.11g and the actual yield was 2.65g, what was the percent vield for the reaction? Show formula and all work. 3. If a melting point range is 119.5°C to 125.8°C, what can you say about the sample? (Exp. 11, version 5) Page 9 of 10

Name Lab Partner LAB 9 REFLECTIVE EXERCISES Lab Section 1 What data did you collect to indicate that you successfully produced aspirin? What did your results indicate about the purity of the aspirin you obtained? Explain your answers. 2 Given that the melting point of salicylic acid is 159 C, can you be certain that the product you isolated was not pure solicylic acid that was unchanged during the reaction? Can you be certain that the product you isolated was...

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...

question 2 and 6 thabk you
Exercises 1. (a) Calculate the volume of 6 M NaOH required to react completely with the amount of methyl salicylate you used. How much of the 6 M NaOH that you used was in excess of the theoretical amount? (b) What volume of 3 M H SO is needed to neutralize all of the disodium salicylate and the excess NaOH present after the initial reaction? How much sulfuric acid was in excess? 2. Refer...
