Blue Bottle Reaction Demonstration
|
Compounds that change color as a result of a change in their pH or oxidation state are called indicators. With this activity, you can illustrate this principle to your students by mixing a solution to introduce oxygen from the air into the solution. When you stop mixing, the reaction will reverse itself and become clear again. You will get instructions, the indicator solution, and two chemicals preweighed for a one liter demonstration. This demonstration can be completed in 20 minutes.
Note: additional shipping fee required.
