CheMagic Demonstration Video: Luminol Reaction
Luminol Reaction: Chemiluminescence is a popular reaction used in outreach presentations because it is a dramatic and visual chemical demonstration. In our version we use LUMINOL (2-aminophthalhydrazide). The reaction is initiated by adding a drop of blood on a sterile alcohol pad (potassium ferricyanide also works) to the luminol. When done in the dark, it is an entertaining chemical demonstration. We explain that this reaction has practical applications in that luminol can be used as a presumptive test for blood in a crime scene investigation. Why not just break open a cyalume stick? Watch this chem demo video and judge for yourself.
