Chemistry 12

Chemistry 12 Course Overview

Big Ideas

Reactants must collide to react, and the reaction rate  is dependent on the surrounding conditions.

Dynamic equilibrium can be shifted by changes to the surrounding conditions.

Saturated solutions are systems in equilibrium.

Acid or base strength depends on the degree of ion dissociation.

Oxidation and reduction are complementary processes that involve the gain or loss of electrons.

Introduction

Chemistry 12 enables students to enrich their understanding of chemistry through the study of how reaction rates, and equilibrium effect chemical systems involving solubility and acids & bases. The field of electrochemistry will also be explored. Students will further develop their problem-solving, virtual laboratory skills and their ability to communicate scientific information. This course is intended for students wishing to study science, engineering, technology, medicine or life sciences at the post-secondary level. This course is an extension of Chemistry 11. A strong background in mathematics and problem-solving skills are essential for success.
