Chemistry: Acids and Bases
These sites focus on acids and bases. Learn the difference between acids and bases and their chemical reactions. There are activities and experiments that help students to learn how to use pH scale and to classify materials as acids, bases, or neutral. There are virtual experiments, interactive games, experimental ideas, animated movies, and quizzes. Includes a link to eThemes Resources on mixtures and solutions.
