CHEMISTRY 300 QUANTITATIVE ANALYSIS Fall Semester 2008 e-mail: april.dupre@nicholls.edu Office: 107 Peltier Hall Instructor: April Dupre Phone: 448-4389 Office hours: MW 8-10, TTh 8-12 and by appointment CATALOG DESCRIPTION - Chemistry 300. Quantitative Analysis. 3-3-0. A course in the theory of gravimetric and volumetric analysis, with emphasis on acid-base equilibria and titrations, oxidation-reduction equilibria and titrations, formation and properties, and techniques of analysis. PREREQUISITE/COREQUISITE - Prerequisite: Chemistry 106 and 110. TEXT/REQUIRED MATERIALS – 1. D.A. Skoog, D.M. West, F.J. Holler & S.R. Crouch. Fundamentals of Analytical Chemistry, 8th. edition. ISBN: 0-03-035523-0 2. Scientific calculator GOALS OF COURSE – To provide a background in the chemical principles that are particularly important to analytical chemistry. To develop an appreciation for the difficult task of judging the accuracy and precision of experimental data and to show how these judgments can be sharpened by the application of statistical methods. To expose to a wide range of techniques of modern analytical chemistry. To develop the skills needed to solve analytical problems in a quantitative manner. STUDENT OUTCOME OBJECTIVES - Upon completion of this course, students will be able to: explain the role of analytical chemistry and steps for a typical quantitative analysis. explain terms and calculations involving errors in chemical analyses (mean, median, precision, accuracy, systematic error, random error, gross error, standard deviation, gaussian curve, error propagation, significant figures. explain and express quantities/concentrations of chemicals (SI units, mole, millimole, molarity, wt%, ppm) and perform chemical stoichiometry calculations for chemical reactions. explain the principles and applications of gravimetric methods of analysis. explain the principles and applications of chemical equilibria (complex systems, precipitation titrations, neutralization titrations, and polyfunctional titrations). explain the principles and applications of electrochemical methods (voltaic and electrolytic cells, effect of concentration on cell voltage, standard cell potentials, and batteries). explain the principles and applications of spectrochemical analysis (radiation/matter interaction, instrument components, Beer’s Law). EDUCATIONAL COMPETENCIES COVERED – At the completion of the course candidates will be able to explain and demonstrate the benchmarks related to: measurement and symbolic representation (PS-H-A1) chemical reactions (PS-H-D2 to D4) abilities necessary to do scientific inquiry ( SI-M-A3) understanding scientific inquiry (SI-M-B6, SI-H-B2) TESTING - 3-hour exams (100 pts per test) cumulative with emphasis on the material covered since last test (typically, 8 problems / questions worth 12 pts ea.). These exams will be given in class on or around Sept 22, Oct. 24, and Nov 19. Partial credit will be given for problems worked partially correct; therefore, it is crucial to show your solutions to the problems, not just the answer. Credit will not be given for correct answers unless you show how you arrived at the answer. Final Exam - comprehensive worth 200 pts. (typically, 15 problems / questions worth 13 pts ea.) given on Wednesday, December 3 from 1-3 PM HOMEWORK/QUIZZES – Homework and/or quizzes will total 100 points. GRADING - The final grade will be based upon (sum of exam 1, exam 2, exam 3, final exam , Hw)*0.2. Grading scale - A= 90 - 100%; B= 80 - 89%; C= 65 - 79%; D= 55 - 64%; F= below 54%. WITHDRAWAL FROM THE COURSE – The last day to withdraw from the course and receive an automatic “W” is Friday, October 24. This coincides with the date of exam 2. Students may notify the instructor if performance on this exam is to be used as a deciding factor for course withdrawal, and their exams will be graded prior to the deadline to drop the course. GENERAL EDUCATION TESTING - In order to complete requirements for this course, you must take a test of General Education. Your score on this test has no bearing on your grade in this course. If you fail to take the test, you will receive an I in this class. You must take the test the next semester when offered and your grade will be changed. MAKE-UP POLICY - There will be no make-up exams. ATTENDANCE - Attendance of class is mandatory. A total of four unexcused absences will result in the student being dropped from the class with a grade of "F". CHEATING - Cheating or scholastic dishonesty will not be tolerated. In cases of academic dishonesty the instructor may dispose of the matter by invoking a maximum sanction of immediate expulsion from the course and the issuance of a failing grade. ACADEMIC DISABILITY POLICY: If you have a documented disability that requires assistance, you will need to register with the Office of Disability Services for coordination of your academic accommodations. The Office of Disability Services is located in Peltier Hall, Room 100-A. The phone number is (985) 448-4430 (TDD 449-7002).
