This Test will cover the material since the last test. Subjects include: Precipitation and EDTA Titrations, The Literature of Analytical Chemistry, Real Life Analysis, Complexes, Oxidation/Reduction, Spectrophotometry and Separations. Review the reading guides, the lecture notes, the homework assigned and the quizzes, the textbook and your study notes. Labs that are based on these topics-chloride, copper, iron, real life.

Specifically one needs to review: Chapters 13, 14, 15,16, 17, 22, 24, 26, 31, 32, 33, 34, A-1.

Literature: The Types of literature in analytical chemistry and specific examples. The total process needed in doing a literature search.

Real World Analysis: Specific Problems and Factors to consider.

Oxidation Reduction: Definitions, Nernst equation, concentration factors, half cells, chemical equations, applications.

Spectrophotometry: Beers Law, Quantitation, Limitations, Applications, Titrations

Separations: Types, Equations, Goals and limitations, Tips.

A suggestive but not necessarily an inclusive list of thought questions:

1. The problems and joys of samples from everyday life.

2. Requirements for redox, precipitation, complexometric, and spectral titrations.

3. How does one choose an indicator for a redox, precipitation or a complexometric titration.

4. Discuss the role of indicators in redox, precipitation and complexometric titrations.

5. Discuss the role of pH in titrations: redox, spectral, precipitation and complexometric

(Is there a universal pH?)

6. Discuss the role of oxidation state in Redox, Spectral and Spectral Determinations.

7. Discuss the role of matrix in redox, spectral, precipitation and complexometric determinations.

8. Be able to work with mixtures in redox, precipitation and complexometric determinations.

9. Be able to use Beer's Law

10. Be able to use Excel regressions with Beer's Law.

11. Know the difference between a Walden (Ag) and Jones (Zn) reductor.

12. Apply the Nernst Equation.

13. Balance Redox Equations.

14. Calculate Spontaneous Reactions, Keq, and E at equivalence point.

15. Discuss Interferences.

16. Discuss Deviations form Beer's Law.

17. Discuss the factors needed for liquid/liquid separations.

18. Discuss the role of separations and alternatives.

19. Compare and Contrast the various types of Chemical Literature.

The test will probably be 30-40% discussion or verbal and 60 to 70% numerical problems.
