What happens to the oxides of sulfur and nitrogen produced during combustion?
Where do they go and how do they affect the environment? This module is
intended for use in an analytical chemistry course and asks students to
consider the consequences when soil equilibria are stressed. What chemical
species are important in the soil system charge balance? How are changes in
pH, solubility, and ion-exchange interlinked with ion distributions and
concentrations? How does the chemical system shift and the ecosystem respond?
Instead of many simple problems where individual equilibria are studied
separately, students are asked to question and investigate facets of a more
complex problem through laboratory measurements of model and natural systems,
supplemented by case studies.
Tool Kit:
Chemical Principles:
* Equilibria (Le Chatelier's Principle, gas equilibria, solubility, acids and bases, buffers, redox reactions, distribution equilibria)
* Laboratory Procedures (analytical methods, instrumental techniques)
Thinking Like a Scientist:
* Experimental Design (sampling, controls/calibration)
* Data Analysis (statistical analysis of data, analysis of the impact of the results on society)
* Critical Thinking/Problem Solving (reasoning, order of magnitude estimates)
* Systems Modeling (simulations, computation of complex interactions)
* Communicate Results (writing, speaking)
Audience: sophomore analytical chemistry
Prerequisites: ions, moles, acids/bases, Lewis structures, oxidation states, and equilibria
Interdisciplinary components: Aspects of this geochemistry module belong to geology, biology, and chemistry. "What happens to acid rain?" is an international question and studies/data from outside the US will be extensively used.
