Ward's® Chemistry Oscillating Yellow and Blue Solution Demonstration
Educational Classroom Kits and Activities
Teach Basic Chemical Concepts in a Fun, Visual Way.
- Can be performed in just 10–30 minutes
- Requires only basic labware that you provide
For this demonstration you simply place a flask containing a yellow solution on a magnetic mixer and watch the solution turn from yellow to blue and back to yellow. The reaction will continue to oscillate for 10–15 minutes. Give your students a visual representation of a redox reaction and teach them about the chemical reaction concepts while enjoying the color changes.
