How Do Indicators Work?

  • Classic AP Chemistry Experiment
  • Instructions Included
pH is the measure of the concentration of hydrogen ions in a solution. As this concentration can extend over several orders of magnitude, it is convenient to express it by means of logarithms of base ten. Certain pigments change color with a change in pH. In this experiment we will extract pigments from various sources and determine if they are sensitive to changes in pH.

Ordering information: Includes Hydrochloric Acid, Sodium Hydroxide, Isopropyl Alcohol, and Acetone.
