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 numerous examples of acid and base applications—cleaning agents, electric batteries, stomach antacids, and indicators in analytical chemistry experiments. Viewers will find the video’s lively demonstrations and their use of everyday objects and materials particularly helpful. Viewable/printable educational resources are available online. (31 minutes)
