This program from VEA familiarises students with the features of acids and bases, and discusses their physical and chemical properties. The pH scale is introduced with examples of strong and weak acids and bases and the concept of neutral substances is explored. The use of indicators to test the pH of acids and bases is explained, as well as showing the variety of indicators available and their specific uses.
Students are shown how to make their own red cabbage indicator in the kitchen, and examples of acids and bases commonly found in the home are discussed. A description of neutralisation reactions and their products concludes the program.
