Chemistry

Discusses the different theories of acids and bases, including Arrhennius theory (Chem 20), Brønsted-Lowry theory (Chem 30), and Lewis theory (Post-secondary).

Defines acids and bases, discusses strength and pH, defiines terms, and gives example problems.

Videos and problems from Khan Academy on buffers, strong and weak acids, and titrations. Recommended for Chem 30 students

A worksheet from Holt ChemFile: Problem-Solving Workbook.

This online quiz is intended to give you extra practice in calculating pH and pOH from hydrogen ion (H+) and hydroxide ion (OH-) concentrations and vice versa.
