CIA Demonstration: Luminol (7.1.3)

Question 1

• The reaction of luminol with hydrogen peroxide is exothermic, but gives off energy as light instead of heat or work.

Answer 1

• The reaction of luminol with hydrogen peroxide is exothermic, but gives off energy as light instead of heat or work.

Question 2

Luminol (3-aminophthalic acid hydrazide) is oxidized
by hydrogen peroxide. This is an exothermic
reaction.

While most exothermic chemical reactions deliver
energy as heat or work, the oxidation of luminol
delivers energy as photons of light. Chemical
reactions that emit light are called
chemiluminescent reactions.
