D EPARTMENT OF C HEMISTRY AND B IOCHEMISTRY Q UALIFYING E XAMS The Department of Chemistry and Biochemistry at Clark utilizes exams prepared by the American Chemical Society (ACS) in five separate areas of chemistry: Analytical Biochemistry Inorganic Organic Physical All exams are multiple choice. They last two hours each. To complete the departmental requirement, you must pass four of the five exams within one year and not more than three attempts. Each exam is scored individually, with most scores being simply the number of correct answers, but some involving a penalty for incorrect answers. You will be told before taking the exam how they are scored. In most cases you should try to answer all questions, but in some instances you should only guess when you can narrow the choice to two answers. Below are some brief comments on the general areas covered by the exams. For more detailed descriptions on how to prepare for these exams, please feel free to contact individual professors in the department. Analytical Chemistry (Prepared with the help of the ACS Division of Analytical Chemistry) A sequence of courses designed to cover modern analytical chemistry at the undergraduate level should present an integrated view of the theories and methods for solving a variety of real problems in chemical analysis. Students should receive a coherent and progressive treatment of the various aspects of problem definition, physiochemical operations and data evaluations. The problem oriented role of chemical analysis should be emphasized throughout the student's experiences. (The appendix material for Computers in Chemistry should also be consulted. Additionally, the Analytical Chemistry Subcommittee of the Division of Chemical Education Curriculum Committee has prepared an extensive document with performance objectives for analytical chemistry.) In addition to a firm foundation in basic chemical reactions involving analytes and ordinary analytical reagents, adequate coverage of modern analytical chemistry should include: Distinction between qualitative and quantitative goals of determinations Choice of experimental designs Sampling methods for all states of matter Sample preparation and derivatization procedures
- 2 - Availability and evaluation of standards Standardization methodology Theory and methods of separation Physicochemical methods of measurement Fundamental characteristics of instruments, including recording devices and data acquisition options Comparison and critical selection of methods for both elemental and molecular determinations Optimization techniques for various aspects of analysis Methods of data evaluation Individual topics should be presented in the framework as a systematic approach which emphasizes functional roles, facilitates comparison of performance characteristics and provides a pattern the student can use to understand related topics not included in formal course work.
