TERM: 2020/21 Winter
COURSE NUMBER: CHEM 312
COURSE TITLE: Analytical Chemistry II (formerly CHEM 310)
NAME OF INSTRUCTOR: Dr. Leah Martin-Visscher
CREDIT WEIGHT AND WEEKLY TIME DISTRIBUTION: credits 3(hrs lect 3 - hrs sem 0 - hrs lab 3)
COURSE DESCRIPTION: This introduction to quantitative analytical chemistry particularly emphasizes the modern instrumental techniques of spectroscopy and chromatography important to both chemistry and biochemistry. Spectrophotometry, solvent extraction, liquid chromatography, high-pressure liquid chromatography, gas-chromatography, and potentiometry utilizing ion-selective electrodes are among the methods studied. An introduction to questions of precision, accuracy and sampling will also be given.

OBJECTIVES: Learning outcomes are statements that describe the key content, skills or values that you will be able to  demonstrate, or describe, upon completing the course. This course, though a combination of lecture and  laboratory experiments, is designed to help you answer questions about measurement in chemistry. At the end of this course, the successful student be able to:
  • Describe and operate key instruments in chemistry lab, with a focus on:
    • Explain how the instrument works by referring to fundamental chemical and physical principles (A, B)
    • Describe the applications of the instrument in chemical analysis, including limitations (C)
    • Demonstrate proper use and care of the instruments (C, F)
  • Analyze and quantify the component(s) in a sample by:
    • Selecting appropriate analytical instrumentation (A,B)
    • Planning and carrying out a suitable laboratory procedure, including the preparation of standard solutions and calibration methods (A, B, C)
    • Demonstrate the correct use of instrumentation and volumetric glassware (C)
    • Interpretation of spectroscopic data (A,C)
    • Use spreadsheets to perform calculations and prepare graphs (A,D)
  • Effectively communicate laboratory results in oral and written form (notebook, scientific reports, presentations) (D)
  • explain the basic principles of electrochemical methods (A)
  • describe the use potentiometry, coulometry, or voltammetry to analyze chemical samples (A,B)
Note – Each learning outcome for Chem 312 has an associated code (A-F). These codes group learning outcomes into six major categories, as follow:

A. Depth and Breadth of Knowledge
B. Knowledge of Methodologies
C. Application of Knowledge
D. Communication Skills
E. Awareness of the Limits of Knowledge
F. Maturity and Professional Capacity
