Product Details

Captivate students’ attention with four “enlightening” demonstrations about chemiluminescence! • When light is produced without heat, that’s cool! Pour two solutions together to illustrate the light-producing reaction that takes place when luminol is oxidized.

• Astonish students with Energetic Lights’ ability to exhibit luminous longevity!
• Students will be de“lighted” as the same solutions appear a different color when exposed to a black light than when exposed to white light.
• Ignite students’ understanding of atomic emission! Observe the different color light produced as various salts are heated to their excited states.

Concepts: Chemiluminescence, oxidation–reduction, catalysts, fluorescence, absorbance, transmittance, emission, excited versus ground states, atomic emission.
Time Required: One full class period.
Chemicals Provided: Calcium chloride, copper(II) chloride, energetic light solution, eosin Y solution, ethyl alcohol, fluorescein solution, hydrogen peroxide, luminol, potassium ferricyanide, rhodamine B solution, sodium chloride, sodium hydroxide solution, tonic water.
