Abstract
- General chemistry students can learn from an intriguing and elucidative experiment involving color changes in indicator solutions. Students often learn more about a subject when observations contradict expectations. In this experiment they can learn about acid-base indicators and about dilution. Using pH measurements and analyzing the electronic sectors of the indicator solution can show that the behavior is in agreement with equilibrium concepts. The main characteristics that a system must have to show a similar phenomenon and the effects of dilution on color are discussed.
