Panacetin Lab Write Up
laboratory Report Format for Separating the Components of Panacetin (2) and Recrystallization and resolve evince Measurement Identifying the Components of Panacetin (3). Lab Notebook Title and Date Objective exc persona the purpose of the experiment and how you plan to accomplish it. Technique Show the use of separatory funnel and evaporation of solvent setup Reaction(s) Include the main chemical reaction for the experiment and isolation scheme Physical information List the molecular(a) weight, melting point, boiling point, density, solubility, and hazards of all pertinent chemicals used in the experiment.selective information/Observations Your observations of the experiment, a. pitch of sign panacetin sample. b. pitch of sucrose collected. c. Weight of aspirin collected. d. Weight of inexplicable compound isolated e. Weight of recrystallized unknown compound f. liquescent point range of recrystallized unknown compound. g. TLC sketches with appropriate data for Rf calculati ons (Clearly testing groundel each column of spots on the page so I know what it is) h. Mixed melting point establish on information from TLC Final Report ? Title Page.Include (1) the title of respect of the experiment, (2) your name, (3) the due date, and (4) the date submitted ? Purpose of the Experiment. ? Background/Setup ( 1 page) ? wrangle extraction system and explain the general operation of the equipment ? Explain the theory behind isolation scheme ? Explain the purpose of recrystillization ? Procedure reservoir the procedure (i. e. text or handout) and any changes that deviated from the original reference ? Data and Results o Physical description for substance(s) isolated o Weight of initial panacetin sample. o o o o o o o o oWeight of sucrose collected. Weight of aspirin collected. Weight of unknown compound isolated Weight of recrystallized unknown compound Melting point range of recrystallized unknown compound. Mixed melting point based on information from TLC TLC Cross reference with lab notebook Rf values from TLC (including the solvent used) Percent recuperation of sucrose, aspirin and your unknown ? Calculations Show sample calculations of the percent recoveries of sucrose, aspirin and your unknown and Rf calculations. ? Discussion. What was the identity of your unknown?Explain in detail how you find it, comparing the data you obtained with known values. Explain any discrepancies. (1 page) ? Conclusion draft statement with final conclusion (restating the goal of the lab and summarizing important data showing that the goal was or was not achieved) ? Excercises Lab 2 questions 1,3,5 Lab 31 and 2 Additional Question Where in the musical interval procedure could you lose one or more of the Panacetin particles? Explain which component could be lost in which step. Ignore trace amounts left in containers, or blatant spills.
