Instructor: Dr. David Carter Syllabus CHEM 3421 Inorganic Quantitative Analysis Fall 2017 Office hours: M/F 9:00-10:30 AM, W 8:30-10:30 AM or by appointment Office: CAV 218 Office Phone: 486-6626 email: david.carter@angelo.edu Course web site: http://blackboard.angelo.edu Class times: MWF 11:00-11:50 A.M. CAV 223 Lab: Thursday 2:00-4:50 P.M., CAV 206/200 Texts: REQUIRED EBook/Online Homework Sapling Learning Online Homework + EBook: Quantitative Chemical Analysis, 9 th Ed., Daniel C. Harris. Note: both the ebook and online homework will also be used for Instrumental Analysis (CHEM 4421). If you plan on taking Instrumental at ASU, purchasing two semesters of the online homework and the two year option for the ebook will provide substantial savings. Optional hard copy book options: textbook can be purchased in same edition, but older additions are significantly less expensive and will work well if you have the Ebook. Supplemental Text: Analytical Chemistry 2.0, David Harvey, 2008 http://dpuadweb.depauw.edu/harvey_web/etextproject/version_2.1.html Other Materials: The Official Laboratory Research Notebook Safety Goggles Learning Outcomes 1. Survey fundamental methods of Quantitative Analysis. (1a) * 2. Develop an awareness of the fundamental steps required to perform a quantitative chemical analysis and an understanding of the role that each step plays, its importance and its logical place in the sequence of steps that comprise a chemical analysis. (3a) 3. Develop an understanding of the application of chemical equilibrium to quantitative analysis in order that students may assess the feasibility of a method and be able to troubleshoot analytical methods. Students should understand analytical methods from an equilibrium perspective. (1a,2b,c) 4. Use the principles or stoichiometry and dimensional analysis to do the computations necessary to convert the data of a chemical analysis into meaningful quantitative information. (2b, 3a) 5. Learn how to use statistical methods in data analysis to estimate the precision and accuracy of analytical results. (2a) 6. Develop physical laboratory skills needed to perform precise and accurate quantitative analyses. (3b) 7. Understand the importance of the application of quantitative chemical analysis to other sciences and that the principles learned in this course are essential to the quality of experimental work done in other science disciplines. (4a,2c) 8. Improve student ability to plan, implement, record, and report experimental work effectively. (2a) 9. Train students to use spreadsheets for a wide range of scientific calculations. (2d) 10. Develop insight into the selection of lab equipment required to attain desired levels of precision and accuracy in measurements. Students should be able to select equipment appropriate for a given level of accuracy and precision. (3b) 11. Students should be familiar with methods of standardization and calibration required to achieve required levels of accuracy and will be introduced to the concept and application of quality control in analytical measurements. (3b) 12. Develop working knowledge of acid-base, precipitation, complex formation and redox reactions. (2a,3b) 13. Students will be introduced to principles of working safely with chemicals in the laboratory and chemical hygiene. (3b) Evaluation of Student Learning Outcomes Student learning outcomes will be evaluated by test questions and by the grading of other lab notebook, reports and other assignments. * Number-letter notations in parentheses after each objective refer to the Student Learning Objectives of the Department of Chemistry and Biochemistry. These are available in the Course Information section of Blackboard.
Syllabus CHEM 3421 2 Grading Homework and Quizzes Exams (3 X 100 pts ea.) Lab Final Exam Total 200 pts 300 pts 500 pts 200 pts 1200 pts Student Responsibilities 1. Attendance. Class attendance is expected. The student is responsible for making-up any work missed due to absence from class. The student will only be permitted to make up missed work under the following conditions: a. Unavoidable emergency absences (illness, death in the immediate family, etc.): you must contact me during or before the class immediately following the absence with a valid, verifiable excuse. b. Planned absences (trips out of town, etc.): you must get my approval make arrangements to make up missed work prior to the absence. The reason for the absence should warrant missing class to get my approval; participation in University sponsored events would fall in this category. c. A student who intends to observe a religious holy day should make that intention known in writing to the instructor prior to the absence. 2. Class Preparation. Read each reading assignment before it is covered in class; come to class prepared to discuss the material. Contribute to in-class discussions of the material. 3. Homework and Quizzes. Do all assigned homework problems whether they are graded or not. During the class that immediately follows the giving of an assignment, you may take the opportunity to ask questions of that assignment at the start of the class. After they are graded or discussed in class, make sure you understand them. Quizzes may not be announced. When they are unannounced, they may be over the two most recent homework assignments or over the last two lectures. Therefore, it is to your advantage to get an early start on each assignment and to review your class notes between lectures. 4. Exams. Demonstrate your knowledge and understanding of the material covered on exams. All exams are cumulative; however, regular exams will predominantly (usually > 90% of exam) cover material covered since the last exam. 60% of the Final Exam will be material covered since Exam 3, and 40% will cover material already covered on previous exams.. Exams cannot be made-up, except in the following circumstances: a. Previous arrangements are made with me b. Serious illness (note from a physician, etc. required) c. Death in the immediate family 5. Laboratory. Laboratory work is an essential part of a science course. Students should make every effort to participate fully in the laboratory experience. Material from lab experiments may be covered on lecture exams. 7. You must show all work when doing mathematical problems on the homework, on tests and in the lab. 8. All numerical answers must be written with the correct number of significant digits and appropriate units. Academic Honor Code Angelo State University expects its students to maintain complete honesty and integrity in their academic pursuits. Students are responsible for understanding the Academic Honor Code, which is contained in both print and web versions of the Student Handbook. Special Accommodation "Persons with disabilities which may warrant academic accommodations must contact the Student Life Office, Room 112 University Center, in order to request such accommodations prior to any accommodations being implemented. You are encouraged to make this request early in the semester so that appropriate arrangements can be made."
Syllabus CHEM 3421 3 Laboratory Assignment Grading Grading of laboratory assignments will be based on three criteria: lab report (notebook), accuracy and precision. The number of points varies for each of these as a function of the laboratory. For example: some of the methods used should yield accuracies within 1 part per thousand (1 ppt or 0.1%) of the correct value. The number of points given for accuracy in these labs will be higher than other labs. Some labs are more qualitative in nature and more points will then be given for the lab report. The points assigned for each lab are given below. Lab Accuracy Pts Precision Pts Report Pts Total Pts Excel Intro --- --- 10 10 Buret reading statistics --- --- 10 10 Penny mass stats --- 10 30 40 Pipet Calibration --- 10 20 30 NaOH Standardization --- 10 10 20 HCl Standardization --- 10 10 20 KHP Unknowns 50 10 10 70 Water Analysis - Alkalinity 5 5 10 20 Experimental Acid-Base Titration Curves 5 5 30 40 Redox Titration Standarize KMnO 4 0 10 10 20 Oxalate Unknown 50 10 10 70 Measurement of ph 10 0 40 50 Mn in steel 10 5 25 40 Calib.
