Unit 1: Chemical Systems and Equilibrium<br />

Time: 30 hours<br />

Unit Description<br />

In this unit, students increase their understanding of solutions to incorporate equilibrium systems.<br />

Students investigate the behaviour of different equilibrium systems, e.g., liquid-vapour, insoluble salts,<br />

weak acids and bases, and solve problems involving the law of chemical equilibrium. Le Chatelier’s<br />

principle is used to predict how various factors affect a chemical system at equilibrium. Students explore<br />

the importance of equilibrium systems in their daily lives, e.g., how equilibrium systems optimize the<br />

production of industrial chemicals and the role they play in biological systems. Throughout the unit the<br />

teacher leads students to use more independent learning strategies, e.g., students generate their own notes<br />

and compare these with teacher expectations. In the End-of-Unit Task, students use their titration skills<br />

and their understanding of molar solubility and the common ion effect to determine an unknown<br />

concentration. Students also complete a written test.<br />
