The lecture includes a comprehensive study of the principles and techniques of the laboratory procedures as well as the theoretical basis of gravimetric, volumetric, and instrumental analysis. The laboratory consists of a series of quantitative determinations of elemental unknowns by classical and instrumental methods.

IV. Student Learning Outcomes

Upon completion of this course, a student will be able to:

  • Demonstrate general fundamental understanding of statistical calculations involved in data analysis and reduction including rejection of data and comparison of data sets;
  • Demonstrate general fundamental understanding of the terminology and application of various quality control parameters that might be used in a laboratory and the limits and advantages of each;
  • Demonstrate general fundamental understanding of the various types of errors such as systemnatic and random errorsin ovlved in chemical analysis as well as how to test for and correct such errors when they occur;
  • Demonstrate general fundamental understanding of unit conversions, solution preparation, and glassware calibration as might be used in a chemical laboratory;
  • Demonstrate general fundamental understanding of the preparation, use and data analyses involved in calibration curves;
  • Demonstrate general Fundamental understanding of various types of laboratory notebooks as well as use of external and internal chain of custodies;
  • Demonstrate general fundamental understanding of activity coefficients and ionic strength and how it impacts the chemical measurement process;
  • Demonstrate general fundamental understanding of the classical wet chemical methods of gravimetric analysis, acid-base analysis, oxidation-reduction analysis and compleximetric analysis;
  • Demonstrate general fundamental concepts of analysis involving macromolecular, Supermolecular, and Nanoscale (MSN) systems;
  • Demonstrate basic understanding of the principles of operation and data analysis for instrumental methods of analysis including most of (but not limited to) the following: UV-visible spectrophotometry, various chromatographic techniques, mass spectroscopy, atomic spectroscopy including plasma spectroscopy.

V. Topical Outline (Course Content)

A course in quantitative analysis should cover the following concepts. Some concepts may be only covered in minor detail and some in significant detail depending on the instructor. Chemical apparatus and unit operations Spreadsheets Random and systematic errors Statistical treatment of data Standardization and calibration Gravimetric methods of analysis Acid base methods of analysis Complex acid base titrations Compleximetric and or precipitation methods of analysis Oxidation reduction titrations Potentiometry Analysis of nano-scale materials Molecular spectroscopy Atomic spectroscopy Mass spectrometry Gas chromatography High performance liquid chromatography Miscellaneous separation methods

Required Assignments

CHEM 253 CLASS Homework as applicable should be assigned from each major topic as outlined in the CLASS LEARNING OUTCOMES given above. A particular homework assignment may cover one or more of the topics. The assignments should constitute at least 10% of the overall CHEM 253 grade. CHEM 253 LABORATORY The CHEM 253 lab should meet for 6 hours per week. This can be done as 1 lab of 6 hours in length or 2 labs of 3 hours in length at the discretion of the instructor. It is assumed that the majority of the experiments performed in CHEM 253 will take 6 hours to perform and some may take 9 or 12 hours. The number of experiments performed should be at least 10 and should cover the topics listed in the LAB LEARNING OUTCOMES as given above. An individual experiment may cover multiple topics. For example an acid base titration can also include data analysis and spreadsheet components. The CHEM 253 laboratory should constitute at least 40% of the total grade for CHEM 253.

Required Exams

CHEM 253 CLASS A minimum of three exams should be given during the semester in addition to a comprehensive final exam. Because the CHEM 253 class is traditionally small, the administration of the American Chemical Society Standardized exam is not required since statistics on small sample sizes are not meaningful. Exams may be open book, closed, book, in class, in testing center, or take home and different formats may be used for different exams during the course of het semester. The Final exam should constitute at least 10% of the total grade for CHEM 253.

Required Text

No specified single textbook is required but the textbook should be of national prominence such as the quantitative analysis books authored by Harris or Skoog and West.

Required Materials

See required tools.

Required Activities

There are no required activities other than the assignments, exams, and laboratory exercises as outlined above.

Assessment Strategy Narrative

Required outcomes assessment will include the following: Exams Homework Laboratory experiments Final exam CSI on-line evaluation
