CHEM 620: Analytical Chemistry Fall 2013 COURSE INFORMATION Instructor: Prof. David Weis 3062A Malott 864-1377 david.weis@ku.edu Office Hours: 3:30-4:30, Tuesday and Thursday, 3062 Malott (also by appointment) Class Meetings: Mon, Wed, Fri, 11:00-11:50 AM, 2001 Malott Required materials: Quantitative Chemical Analysis, 8th ed., by Daniel C. Harris scientific calculator Sapling online homework Prerequisites: CHEM 510 (or concurrent enrollment), or 535, or 640, or 648; and CHEM 310, or 339, or 622, or 624; and CHEM 331 or 625; or by permission of instructor Co-requisites: CHEM 621, Analytical Chemistry Lab Course website: http://courseware.ku.edu/ OBJECTIVES 1. 2. 3. 4. Learn how to apply the analytical approach to answer scientific questions. Learn how to evaluate confidence through statistical and error analysis methods. Learn how to quantify analytes using different types of calibration. Understand the principles and use of the instruments of chemical analysis, from basic glassware to modern instruments. EVALUATION Exams (70%). Four exams will be given, all weighted equally. The first three will be given on Wednesdays during regular class meetings. The last exam is a make-up exam and will be given during the scheduled final exam period. Student satisfied with their scores on the first three exams may skip the final exam. In-class quizzes (10%). Short quizzes will be given at the end of some class meetings. The quizzes will be closely related to assigned homework. Your lowest two quiz grades will be automatically dropped when your final grade is calculated. Quizzes will be graded on a streamlined 5 point scale. (0 = absent or irrelevant work, 1 = minimal work, 2-3 = some understanding demonstrated, 4 = minor errors, 5 = no errors) Homework (15%). Homework assignments will be given after most class meetings. Homework will be assigned through Sapling Learning, an online system. The purpose of the assigned homework is for you to put into practice what you have learned and identify concepts that you do not understand. For this reason, homework will be graded on a 75 point basis although 100 points will be available on each assignment. In general, you will have several attempts to correctly answer each question, though there will be a deduction for each incorrect attempt. Homework will be due at 8 AM on the day of the next class meeting. assignments. It will not be possible to earn any extra credit on homework Pre-class reading quizzes (5%). Short online quizzes on the assigned readings will precede most class meetings. These quizzes will close at the start of class. Grading scale. All grade calculations will be done on a percentage basis, hence two exams with different point values will be weighted equally as percentages. The final grade will be a weighted average of the four components. The following grading scale is anticipated: 93-100%: 90-93%: A A− 87-90%: 83-87%: 80-83%: B+ B B− 77-80%: 73-77%: 70-73%: C+ C C− 67-70%: 63-67%: 60-63%: D+ D D− 0-60%: F COURSE POLICIES Attendance: Attendance will not be recorded. Absences from class do not need to be explained. The instructor will not provide notes, handouts, or other materials for students who miss a class. Missed exams and quizzes: A make-up exam will be given during the scheduled final exam period for students who miss one of the three scheduled exams. Your two lowest in-class quiz grades will be dropped automatically when your final grade is calculated. The score drops enable you to miss ONE exam and TWO quizzes for any reason that you think is important. No explanation or documentation is required, but you should reserve these opportunities for an illness or other serious matters. If you need to be absent from an exam or quiz for university business, a religious observance, or other compelling reason, please discuss this with the instructor well in advance. Missed or late homework and pre-class quizzes: Late homework and quizzes will not receive credit. The final homework and online quiz grades will be calculated after dropping the lowest 10% of the assignments (approximately four each).
