Today students conducted Investigation #15: Acids and Bases. They poured out 50 ml samples of six mystery solutions and then added two micropipettes of an indicator to each solution. They also did this with their control of water. They then created a model of the pH scale using their knowledge of Acids, Bases and Neutrals and the patterns they recognized that developed due to the indicator and solution chemically reacting to create a color change.
