The address is http://voh.chem.ucla.edu/. Grading: Grading: (To receive a passing grade (C-), you must complete ALL the experiments and reports and receive at least 50% of the points in the exams category. NOTE: The instructor reserves the right to modify the 50% rule in the exam category at the end of the quarter after all the scores are tabulated. Preparation for lab - prelab assignments 80 21.8% Performance in lab - technique and accuracy of work 40 11.0% End of Quarter Clean Up 5 1.4% Documentation of lab work - lab reports 140 38.4% Understanding of lab – Midterm (IN LECTURE – see below) 50 13.7% - Final Exam (IN LAB – Refer to lab Schedule) 50 13.7% Total Points: 365 100% Lecture Schedule : Mar. 31 Introduction/ Measurements and Errors Apr. 7 Theory on Beer’s Law & Concentration Units Apr. 14 Acid-Base Equilibrium (I) Apr. 21 Acid-Base Equilibrium (II) Apr. 28 Midterm Exam (NO MAKE UP EXAM) May 5 Using Spreadsheets to analyze Titrations Data May 12 Recrystallization & Melting Point Theory (Brief Overview) May 19 Chemical Kinetics June 2 REVIEW FOR FINAL Exam(s) must be taken during the lecture section (or during the lab section if the exam is in-lab exam) in which you are officially enrolled. Any missing exam will count as ZERO. Lab quizzes (if any) must be taken during the lab section in which you are officially enrolled. NO EXCEPTION. There is NO MAKE UP for missing exams regardless of reasons. Lab Preparation: You must be prepared for the experiment before you come to lab if you wish to complete the experiment in the time allotted. The course is impacted; there is neither make-up time in the course nor space for you to work in other sections. If you miss a lab, you MUST discuss the issue with the course instructor to see what other options you may have to complete the experiment. You must do your lab work in your scheduled period. In preparation for the lab, you should first study the pertinent sections in the text, review the lecture notes pertaining to the experiment, then view (and possibly review) the appropriate videotapes (refer to lab schedule) for any new techniques to be used in the experiment. For the pre-lab reports, you should write the introduction, procedure (including a reference to the original source and a flow-chart summary of the experimental steps), and data tables for the experiment in the notebook before the lab section meets. Pre-lab study problems must also be completed (if assign) before your lab section meets. During lab, you will complete the data tables and record any other observations about the experiment. In addition, you may be required to obtain physical properties as well as safety information for different chemicals for each experiment from the on-line MSDS (Material Safety Data Sheets) database. MSDS are available on-line (refer to the MSDS handout). If a pre-lab report is required for the experiment, you MUST turn in the duplicate copy of the pre-lab report to your TA at thebeginning of the lab period. A copy of the in-lab data is to be turned in to the T.A. at the end of the lab period. Late pre-lab work will count as ZERO. (OVER)COURSE INFORMATION (continue) NOTE: Techniques videotapes can now be viewed on the internet (refer to the lab schedule for Web address). Required Texts: (1) Chemistry 14B/CL Lab Manual (2) Introduction to Organic Laboratory Techniques – A Microscale Approach (3rd Edition) by Pavia, Lampman, Kriz and Engel. Recommended Text: Peter Atkins and Loretta Jones, Chemical Principles - The Quest for Insight (2nd Ed) (or any other equivalent general chemistry text) Post-lab Reports: The remainder of the lab report, - the data analysis, error analysis, and conclusions - are to be completed in the lab notebook after the experiment is completed. The original copy of this portion of the report is turned in to the T.A. at the start of the following lab period along with any graphs that have been prepared on fine-grid (millimeter) graph paper. Unexcused late post-lab portions of the reports, will accrue a penalty of five percent of the grade per day for unexcused late reports. No reports will be accepted after 5:00 p.m. on the last day of the instruction. Computer programs used to analyze data must be referenced and copies may be requested by the instructor. Bulletin Board: The course bulletin board is located on the wall across from the vending machines on first floor of Young Hall. Report guidelines will ONLY be available on the 14BL VOH (Virtual Office Hours) homepage. Safety Goggles (OSHA APPORVED) and Protective Clothing: Eye protection must be worn in all laboratories whenever any laboratory work is in progress. Recommended safety goggles may be purchased from the Undergraduate Chemistry Fraternity - AXE - Room 1275 Young Hall. Other styles of goggles are available at local bookstores. A heavy vinyl or rubberized apron or full-length lab coat, closed-toe shoes, and long pants must be worn when doing experimental work. Aprons may be purchased from AXE or the student store. If you wear an apron, your shirt must cover your shoulders and upper arms. Shorts and sandals do not provide adequate protection for laboratory work. You will be barred from the laboratory if you are not wearing appropriate protective clothing. Latex gloves will be provided for those experiments using chemicals that are hazardous to skin. Laboratory Notebooks: Laboratory notebooks designed for duplicate records are available from the Undergraduate Chemistry Fraternity - AXE - Young Hall 1275 and the student store. All experimental data and complete reports will be recorded in this laboratory notebook. Note: AXE only accepts personal check when purchasing lab equipment. AXE DOES NOT accept cash or credit card!
