COURSE: Chemistry 12, University Preparation
Unit of Study: Chemical systems and Equilibrium
Course Code: SCH4U
Summary
Overall Expectations
This unit focuses on the
concept of systems in
equilibrium and the application
of these systems to chemical,
ecological, biological, and
industrial applications. The
properties of these systems are
examined and the factors that
affect the extent of a chemical
reaction are described.
Experimentally, students will
determine equilibrium
constants and perform acidbase titrations. The knowledge
of systems in equilibrium will
allow students to better
understand acid-base
chemistry, as well as the
solubility of compounds and
their importance to qualitative
analysis.
A1. demonstrate scientific investigation skills (related to both inquiry and research) in the four areas of skills
A2. identify and describe careers related to the fields of science under study, and describe the contributions of
scientists, including Canadians, to those fields
E1. analyse chemical equilibrium processes, and assess their impact on biological, biochemical, and
technological systems;
E2. investigate the qualitative and quantitative nature of chemical systems at equilibrium, and solve related
problems;
E3. demonstrate an understanding of the concept of dynamic equilibrium and the variables that cause shifts in the
equilibrium of chemical systems. (1)
Big Ideas
“Chemical systems are dynamic and respond to changing conditions in predictable ways. Applications of chemical
systems at equilibrium have significant implications for nature and industry.” (1)
