Description
- Observe the beautiful chemiluminescence of luminol
- Provide a visual example of light emission due to a chemical change
- Explore real-world applications of chemiluminescence
Students observe chemiluminescence and explain how electrons release energy during their transition from an excited state to their ground state with this popular demonstration. Amaze your students when you mix a dry luminol mixture with water to produce a beautiful blue glow. A second demonstration simulates presumptive blood testing. Easy preparation and procedure makes this a hit with teachers. Big Picture Questions and a particle-level explanation solidify students’ grasp of the concepts including redox reactions, electromagnetic radiation, and the conservation of energy. This demonstration requires approximately 15 min, and materials are sufficient for 5 demonstrations.
