CHEM 253 Quantitative Analysis*
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 seris of quantitative determinations of elementalunknowns by classical and instrumental methods. Prerequisite:
CHEM 112,
MATH 143. Corequisite:
CHEM 253L.

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
VI. Delivery Methodologies
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
