CheMagic Demonstration Video: Luminol Reaction
Luminol Reaction: Chemiluminescence is a popular reaction used by chemical demonstrators because it is a dramatic and visual 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 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 the video and judge for yourself.
