Chabot College Fall 2010 Course Outline for Chemistry 5 QUANTITATIVE ANALYSIS Catalog Description: 5 - Quantitative Analysis 4 units Emphasizes the theory and practice of gravimetric, volumetric, potentiometric, spectrophotometric and chromatographic methods of analysis. Focuses on calibration, standardization, method development and validation procedures, sampling and data handling. Intended for chemistry, biochemistry, chemical biology, chemical engineering, pharmacy, biology, molecular biology and microbiology majors. Prerequisite: Chemistry 1B (completed with a grade of “C” or higher). 2 hours lecture, 6 hours laboratory. [Typical contact hours: lecture 35, laboratory 105] Prerequisite Skills: Before entering the course the student should be able to: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. solve problems involving gas phase equilibria; determine the extent of acid-base, precipitation and complex equilibria; interpret reactions in terms of Arrhenius, Bronsted-Lowry and Lewis acid-base theory; predict whether oxidation-reduction reactions will occur and set up voltaic and electrolytic cells; describe factors that affect the rate of chemical reactions and match mechanism with reaction rates; describe current models for the bonding of coordination compounds; perform problems involving complex ion equilibria; describe changes that occur in the nucleus of atoms; identify organic compounds and simple isomers; analyze properties of family groups of the periodic table in terms of chemical principles; perform titrimetric experiments; measure pH with the use of pH meter or indicators; perform quantitative laboratory experiments in an accurate and precise manner; perform qualitative analysis of anions and cations in the laboratory; collect and analyze scientific data, using statistical and graphical methods; use a visible spectrophotometer; perform laboratory experiments in an efficient, safe, and purposeful manner.
