Lab Manual:

The Identification of an Organic Acid, 4th Ed. (Given on 1st day)

Laboratory Materials Required: A bound/stitched notebook (NO SPIRALS NOR TEAR OUT PAGES); Safety goggles or safety glasses (purchasable in lab). Comments on Lab: 1. Students are expected to attend EVERY pre-lab lecture. NO MAKE-UP LABS. 2. Safety goggles/glasses and a lab apron must always be worn during lab sessions. 3. Bound stitched composition notebook is mandatory. a. Bound composition notebook required. Pages cannot be torn out. b. Everything in the notebook must be written in pen and kept up to date. c. Leave the first two pages of the notebook blank for the Table of Contents. d. All pages must be numbered, dated and initialed at the top right corner. e. Do not write on other pieces of paper and transfer data to the notebook. Do not tear out pages, or whiteout/markout data. Instead cross-out the incorrect data and present corrected data on another blank page. f. Notebooks must be signed by TA’s or lab instructor at the beginning and conclusion of each lab session. 4. All Quizzes and Exams will be closed book. 5. Cleaning up is part of the lab session. Students should stop working and begin cleaning up their work area no later than 20 minutes before the conclusion of the lab session. Students must exit the lab by 5:00 PM. 6. Students must turn in reports on density, melting point, molarity of NaOH and HCl, and Equivalent Weight of unknown after the conclusion of each of these experiments. Session 1

Introduction, safety video, check-in.

Session 2

Density experiment

Sessions 3-12

October 15th, 2019 is the semester mid-point and last day to drop the course with a ‘W’. If you drop the lecture, you must drop the lab as well. Grading: Final Exam Notebook Study Questions & Quizzes Density Data Sheet Final Report (quality) Identifying Unknown Acid Recrystallization & % Yield EW, NaOH & HCl calc. Computer Search & Analysis pKa Titrations & Sodium Fusion Identification (Logic) TOTAL (Maxiumum)

90* 20* 30 20* 60* 20* 40* 70* 10* 30 10 400 pts (divide by 2 to obtain lab points for semester grade)

*These items are REQUIRED to be completed before total points will be assigned. Note: The Total from the above grading scheme will be divided by two for actual credit (see page 14 in lab manual for details). Thus, the total maximum assignable points of 400 is equal to 200 credit points, which will be applied to your overall CHEM 1211K Course Grade....
