Overview: In maintaining quality of life, society is becoming increasingly reliant upon chemical substances of life. These chemicals and their by-products can also adversely affect the environment and living systems. A knowledge of chemistry is essential to fully understand the benefits and risks of chemicals to humankind and in monitoring the emission of these substances into the environment. In this unit, students examine the impacts of acids and bases, organic compounds and air pollutants on aquatic and terrestrial ecosystems.
Key Concepts: The following concepts are developed in this unit and may also be addressed in other units or in other courses. The intended level and scope of treatment is defined by the learning outcomes.
• acids and bases
• pH and hydronium ion concentration
• stoichiometry and titration of strong monoprotic acids and strong monoprotic bases
• buffers and buffering capacity
• sources and environmental impact of SOx, NOx, acid deposition and photochemical smog
• sources, uses and environmental effects of organic compounds
• biomagnification and persistence of pollutants

Study GuideThe study guide will be introduced at the beginning of each unit and will serve as a pre-and post assessment. this assessment will become a student self-assessment where you will identify areas of strength and areas still in need of attention
|
NotesAlong with the unit notes is a set of skeleton curricular notes. these notes are to be completed throughout the unit and utilized as a study reference for the diploma exam.
|
Unit ProjectsThe multiple Intelligence projects cover all the curricular outcomes int he unit. The projects will not be assessed unless you utilize your MI strengths as identified at the beginning of the year. Dipping into your own creativity can boost engagement levels and deepen overall understanding of content. Enjoy!
