Details about this class
Course Description
Builds upon the principles presented in CH 222Z, explores thermodynamics and chemical equilibrium, and applies them to the study of aqueous acid-base reactions, solubility, and electrochemistry. CH 223Z is a lecture course; CH229Z is the laboratory component. Must be co-registered with CH 229Z. To satisfy the lab science requirement, both CH 223Z and CH 229Z must be completed with a grade of C or P or better. This course is part of Oregon Common Course Numbering. Prerequisites: CH 222 or (CH 222Z and CH 228Z). Corequisites: CH 229Z. Audit available.
Intended Outcomes for the course
Upon successful completion of the course, students should be able to:
- Apply concepts of thermodynamics to explain the favorability of chemical reactions.
- Apply the principles of spontaneity, entropy, free energy, and the laws of thermodynamics to predict and rationalize the behavior of chemical reactions.
- Interpret the behavior and relative strengths of acids and bases, buffers, and the hydrolysis of salts.
- Analyze and evaluate equilibrium reactions including solubility, acids and bases, and other equilibria.
- Predict responses of various chemical systems to changing conditions using equilibrium calculations and Le Chatelier’s Principle.
- Use redox reactions and electrochemical principles to determine cell potentials and to analyze the relationship between voltage, free energy, and equilibrium.
- Identify or formulate and apply the appropriate equations related to electrochemistry, thermodynamics, equilibrium reactions, acids, bases, and buffers.
Technology
There is no additional technology required for this class.
No show policy
Your instructor can mark you as a "no show" if you do not participate in your class during the first week. This will remove you from the class.
