Catalog Description: Theory and application of classical quantitative analysis techniques, including gravimetric, titrimetric, potentiometric, visible spectrophotometric, and liquid-liquid extraction methods as applied to organic and inorganic material. Introduction to statistical treatment of experimental data and development of comprehensive understanding of solution equilibria. Substantial laboratory component provides hands-on experience with each method, applied to the assay of real samples. Prerequisites: Chemistry 114 and 220.2 or permission of instructor. Spring. Two 70-minute periods, two 3-hour laboratories.
To encourage the student to develop system and precision in laboratory technique.
To review and expand upon the student’s understanding of some of the fundamental properties of matter which are useful in quantitative analysis.
To provide the student with an appreciation of chemistry as an exact science.
To further refine the student’s ability to intelligently apply a body of information to the solution of real or hypothetical problems.
