General Information

Required Text: Daniel C. Harris Quantitative Chemical Analysis 6th Edition, W. H. Freeman and Company, New York 2003

Course Content: This is a lecture course addressing aspects of modern chemical analysis with an emphasis on chemical equilibrium. Volumetric, gravimetric, and instrumental methods are described.

Learning Objectives:

• Comprehend the importance of stoichiometry, chemical equilibrium and kinetics in analysis.
  
• Formulate concepts of validation of data and experimental design
  
• Comprehend concept of and perform chemical measurement calibration
  
• Apply and assess concepts of availability and evaluation of analytical standards and formulate standardization methodology
  
• Demonstrate knowledge of sampling methods for all states of matter
  
• Use statistical methods for evaluating and interpreting data
  
• Assess sources of error in chemical and instrumental analysis and account for errors in data analysis
  
• Recognize interferences in chemical and instrumental analysis
  
• Apply theory and operational principles of analytical instruments
  
• Distinguish between qualitative and quantitative measurements and compare and critically select methods for elemental and molecular analyses
  
• Professional Ethics

Lectures: Lectures cover basic statistics, chemical equilibrium, gravimetric analysis, volumetric analysis, acid-base chemistry, complexation, spectrophotometry, and separations.

Homework: Students should work through all Exercises at the end of each Chapter. Certain Problems will be assigned. These Problems should be worked for your own benefit. It is not necessary to work all Problems if you have a good grasp of the concepts and computation skills. This homework will not be graded but the successful student should work them through and check the results.

Examinations: There will be two in class examinations, each worth 100 points, and a final examination worth 150 points. The examinations will be based on homework (Exercises and assigned Problems) and/or concepts addressed in the lectures. The test questions may be taken from the homework verbatim, or may be altered to have different numerical values or reagents. Questions can be synthesized from several homework problems.

Grading: Grades will be based on your performance on the three examinations. Point scores will be added and a percent score calculated. The guaranteed grade cut-off of 90+% A, 80%-89% B, 70%-79% C, 55%-69% D will be used. +/- scores will be used as prescribed in the Catalog. The percentile scores may be adjusted, only upward, to curve the percent scores if the examinations appear to be too difficult and if the class, as a whole, did not perform well on specific questions. Past experience has shown that those students who do the homework and understand what they have done pass with high scores.

Withdrawal Policy: This course will follow the University policy on withdrawals stated in the current Undergraduate Catalog. Drop dates are listed in the Schedule of Classes.

Missed Examination Policy: Students may be excused from an examination in cases of emergency. Documentation must be supplied to be excused. In cases of excused absence, grades will be assigned based on % of adjusted total score. No repetition of examinations is permitted.

Attendance Policy: Attendance will not be taken. Attendance is mandatory for successful performance in this course.

Student Disability Statement: Any student with a disability that requires accommodations must contact the Instructor. The disability must be documented by the Disability Resource Center. Course materials may be requested in alternative formats.

Tentative Lecture Schedule

* The homework problems are in addition to the Exercises that all students should work through. Exercises have worked-out solutions at the end of the book while the Problems may only give the answers.

Notes

• Note on mathematics: Algebra is used in this course. A successful student will be proficient at manipulating equations by the middle of the quarter. Think of algebra as fun!?. There is great satisfaction in obtaining a symbolic result for a complex system.
• A note regarding Chemistry 3610 laboratory: Quantitative Analysis Laboratory is graded separate from lecture. Laboratory performance does not influence lecture grade, or visa versa. Laboratory manuals will be available in the Taggert Student Union copy center. You need to have a manual before coming to the first class since it contains the check in list and the safety agreement. A bound laboratory notebook is required. Students taking the laboratory should read Chapter 2 and Chapter 28 in the text. Pay attention to the use of analytical balances, burettes, volumetric glassware, and sample drying.
