  Analysis, 3rd Ed. and Luther Erickson, Water
  Module Guidebook
• CHM 358 Instrumental Analysis
• Text Skoog, Holler, Nieman, Principles of
  Instrumental Analysis, 5th Ed.

• Polarography of Pb
• Anodic Stripping Voltammetry
• Cyclic Voltammetry
• Rotating Ring Disk Voltammetry
• Impedance Spectroscopy
• Spectroelectrochemistry

11
CHM 130 Text Topics

• Review of Monoprotic Acid/Base Equilibria
• Titrations and Buffers
• Polyprotic Acids
• Activity
• Spectrophotometry and Atomic Spectroscopy
• Transition Metal and Coordination Chemistry
• Chromatography and Mass Spectrometry
• Nuclear Chemistry

12
Water Module Overview

• 5 weeks of lab 4 weeks of class
• Question driven discussion of solubility
  equilibria, carbonate equilibria, atomic
  spectroscopy, and electrochemistry
• Lab analyses of drinking water from around the
  country with Grinnell, Chicago, Des Moines, and
  bottled water providing benchmarks
• Lab concludes with student poster presentations

13
Water Module Class Sessions (Week 1)

• Session 1. Formulating the Questions and
  Limiting the Exploration Focus on Ionic
  Composition
• Session 2. Dissolved Ionic Solids Which ionic
  salts are present in typical water samples and
  how did they get there?
• Session 3. Major species vs. minor species Why
  are so many different concentration units
  employed to describe concentration levels of the
  several species present in water samples?

14
Water Module Class Sessions (Week 2)

• Session 4. Carbon dioxide and dissolved
  carbonates Why do virtually all fresh water
  samples contain bicarbonate as a principal
  species?
• Session 5. Hard water What is meant by hard
  water and why does degree of hardness matter?
• Session 6. Sodium and yellow flames How can we
  determine how much sodium is in the water?

15
Water Module Class Sessions (Week 3)

• Session 7. Galvanic Cells and Ion
  Concentrations How can galvanic cells be used
  to determine ion concentrations?
• Session 8. Potentiometric Titrations How do
  ion concentrations change in the course of a
  titration?
• Session 9. Ion-Selective Electrodes and ppm
  Concentrations How can we determine ion
  concentrations at the 1 ppm level?

16
Water Module Class Sessions (Week 4)

• Session 10. Conservation of Mass and Charge
  Does it all add up? (including poster
  preparation)
• Session 11. What does it all mean? What does
  the complete chemical analysis reveal about the
  source and treatment of our water samples?
• Session 12. Exam

17
Water Module Laboratory
