Acids and Bases
Beyond the general notions of acids and bases introduced in physical science (for example), this advanced review of the topic examines two relevant models: Arrhenius Model, and Brønsted-Lowry Model. Students examine similarities and differences of weak vs. strong acids – and the determination of acidity of a solution. Concepts of titration, the titration curve (also called the pH curve), and discussions of buffered solutions are reviewed.
