water module overview
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
water module class sessions week 1
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?
water module class sessions week 2
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?
water module class sessions week 3
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?

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
