Summary: Filled with simple yet time-tested, instructive experiments, this program-five very visual segments of ten minutes each-illustrates how four important laboratory and industrial chemicals are made and used: hydrochloric acid, sodium hydroxide, ammonia water, and limewater. A fifth segment demonstrates how to dye litmus paper and employ it to test for acidity and alkalinity.

Summary: In the first lesson, five aqueous solutions are tested for degrees of acidity and alkalinity. The nature of acids and bases is examined. In lesson two, table salt is produced by mixing small pieces of aluminum with solutions of hydrochloric acid and sodium hydroxide. Current flow in acid, neutral, and alkaline solutions is demonstrated. An experiment using ammonia water and dry ice tests...

Summary: Use this video to familiarize students with the properties of acids and bases. Beginning with an overview of how these two kinds of chemicals react to or neutralize each other, the program explores Arrhenius's ideas on ion release and Lowry and Bronsted's theory of proton exchange. Details on the pH scale, indicators, conjugate bases, and Lowry-Bronsted reactions are featured along with...
