COURSE NUMBER:

CHEM 311

COURSE TITLE:

Analytical Chemistry I

NAME OF INSTRUCTOR:

Dr. Leah Martin-Visscher

CREDIT WEIGHT AND WEEKLY TIME DISTRIBUTION:

COURSE DESCRIPTION:

This course focuses on the fundamental chemistry underlying quantitative analysis. Particular emphasis is given to the response of a chemical system at equilibrium to changes in various parameters and to the proper collection and treatment of analytical data. The focus in the laboratory is on gravimetric and volumetric techniques.

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:

Evaluate the meaningfulness of data (A,C,E), and assess random and systematic errors, by:

Calibrating volumetric glassware and laboratory equipment (C)

Explaining the complete process, from sampling to measurement and the connection of each step to uncertainty in the final answer (B, C)

Performing statistical analysis (B,C)

Explain the importance of error propagation and statistical analysis in a calculation and how this influences what you can “know” about a sample (E)

Analyze and quantify the component(s) in a sample by:

applying principles of chemical equilibrium to analyze chemical samples (A,B) using acid-base, complexiometric, gravimetric or precipitation titrations to analyze a sample (A,B)

Planning and carrying out a suitable laboratory procedure (A,B,C)

Demonstrate the correct use of instrumentation and volumetric glassware (C)

Use spreadsheets to perform calculations and prepare graphs (A,D)

compare, contrast, and select methods of quality assurance for chemical analysis (B,C,F)
calculate parameters such as chemical speciation, solubility or complex formation using equilibrium constants (A,B)
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)
reflect on and form an educated response to the question of how “uncertainty in measurement” can be used to advantage or disadvantage different groups of people, and the cultural and social impacts of “uncertainty” (E,F)
