Freeman & Co. Chapters: 0 – 10, 12, 27Lecture: CHEM 120-080 9:30 – 10:45 TR Lecture 210 BRLCHEM 120-081 11:00 – 12:15 TR Lecture 210 BRLLaboratory: CHEM 120-082 3:35 - 6:35 W Lab 006 QDHCHEM 120-083 7:00 -10:00 W Lab 006 QDHCHEM 120-084 12:30 – 3:30 R Lab 006 QDHCHEM 120-085 3:30 – 6:30 R Lab 006 QDHCHEM 120-086 7:00 – 10:00 R Lab 006 QDHLab Lecture: Theory of Analytical ChemistryQuizzes during lab lecturePossible small group homework problemsPrevious quizzes, final exams, and solutions are included in notes. Work to numerical answer. Calculator use is essential.Brief Discussions of lab experimentsThe lab experiments will generally be discussed in class on Tuesday before the lab experiment begins on Wednesday. Read each experiment before then and be prepared to discuss the experiment inclass. Laboratory:Attend your regular lab section. No changes in lab sections may be made without permission.Labs can be done in the allotted time and may not require the entire period. You may bring and study other work in lab. You may come and go during lab periods. If you arrive late, do not expect the Lab Instructor to remain late because you have not completed the experiment. The lab sections are tightly scheduled. You may not routinely remain after your laboratory period is completed.The labs may be open on Friday afternoons or Saturday mornings for catch up, make up, and re-doing experiments. If space is available (and with permission) you may work in another other lab period.You may not work in lab without supervision. Reasonable care must be exercised in performing all of the experiments in the laboratory. You must wear safety goggles in the laboratory at all times when anyone is doing any experiment.No additional experiments may be done without Munson's permission.No equipment or chemicals may be removed from the lab.Notebook:You are to keep a NEAT, WELL-ORGANIZED, BOUND LABORATORY NOTEBOOK. The introduction and detailed procedure for each experiment must be written in the notebook PRIOR TO the laboratory session and will be checked by the Laboratory Instructor. The procedure should be sufficiently detailed that you can follow it to do the experiment. You will use YOUR written procedure and not my lab write-up in lab. Notebooks are to be kept current and experiments are to besigned weekly by the Laboratory Instructor. Everything should be written in ink.1Laboratory grading:Both the average value and the best value will be graded. Each result will be graded on a scaleof 2.5 - 5, based on the relative error of your analysis, Ri, compared with the historical average valueof the relative standard error for that experiment, R(avg). A grade will also be given for the precisionof your results, also based on a comparison with results from students in previous years.Laboratory results are to be reported to [email protected], no later than 7:00 pm on the designated days.A deduction of 0.1 point will be made for each day (or fraction thereof) late.A deduction of 0.1 point will be made if the unknown number or other essential datum is missing and the results can be graded.A deduction of 0.3 point will be made for calculational errors.A deduction of 0.5 point will be made if the required number of results is not reported. One value receives only one grade (5.0 max).Accuracy  Ri/R(avg)Grade Ri/R(avg)Grade0.10 5.0 0.80 3.80.15 4.9 0.87 3.70.20 4.8 0.94 3.60.23 4.7 1.00 3.50.27 4.6 1.25 3.40.30 4.5 1.50 3.30.35 4.4 1.70 3.20.40 4.3 1.90 3.10.47 4.2 2.00 3.00.54 4.1 2.50 2.90.60 4.0 3.00 2.80.70 3.9 >3.00 2.5Precision GradeRi/R(avg)  0.50 2.00.50 < Ri/R(avg)  0.80 1.80.80 < Ri/R(avg)  1.00 1.51.00 < Ri/R(avg)  1.30 1.31.30 < Ri/R(avg)  1.50 1.01.50 < Ri/R(avg)  1.80 0.81.80 < Ri/R(avg)  2.00 0.52.00 < Ri/R(avg)  2.50 0.3Ri/R(avg) > 2.50 0.02Repeat Work:You may repeat a laboratory experiment once and submit for a grade. The higher of the two grades will be recorded.Make-up quizzes will be available. The higher of the two grades will be recorded.The grading in this course is the followingLaboratory 60 %Experiments 50 %Notebook 10 %Lecture 40 %Quizzes/Homework 20 %Final Exam 20 %The grading range is the following:A  85A- = 82 - 84B+ = 78 - 81B = 74 - 77B- = 70 - 73C+ = 65 - 69C = 60 - 64C- = 55 - 59D+ = 50 - 54D = 45 - 49D- = 40 - 443LAB POLICIESCHEM119 Honors1. Lab Notebooksa. The Laboratory Instructor will check and sign your notebook each day at the beginning and at the end of the laboratory period.b. Notebooks will be collected and graded during the semester and at the end of the term.c. Notebooks are to be kept current.d. Details of the experiment should be written in the notebook before beginning each experiment: Title, Purpose or Introduction, and enough of the procedures that you cando the experiment from the directions written in your notebook. Do not bring the written handout material from the notes to the lab with you. e. Do not write data on the left hand page and then copy neatly on the right hand page. You should have your notebook sufficiently well organized that you have places on the right hand side to record all of the data in a neat and clearly legible fashion.f. A neat, well-organized, and accurate notebook is beneficial to your grade (10%). The requirements of (d) and (e) above ensure that you know what you are doing when you begin each experiment.g. Notebooks are to be kept in ink.2. Analytical Balances a. The balances must be clean and have readings removed and the doors closed when you havefinished a weighing. b. Hot materials should not be weighed on the balance: reliable weights cannot be achieved.c. Do not weigh anything that has water on the outside of the container. Wet containers lose water rapidly and will not give accurate weights. Water also corrodes the balance pan.d. Do not weigh any solid by transferring the sample to weighing paper on the balance pan. Weigh by difference and do all of your sample transfers outside the balance. If you spill any material on the balance table, clean up your mess!e. The balance doors must be closed to obtain reliable results.f. You should use the same balance for replicate and
