How Does Temperature Affect The Blue Glow Created By The Chemical Luminol

The purpose of this experiment is to investigate and learn how temperature affects the blue glow created by the chemical luminol. Investigating this will help crime scene investigators investigate more effectively and more efficiently. There is a protein molecule in blood called hemoglobin that provides the catalyst that is needed to trigger chemiluminescence which allows a luminol base and hydrogen peroxide solution to be sprayed on a surface to begin giving off an distinctive blue glow if blood is present. To showcase its luminescence, the luminol chemical substance has to be activated. Normally, the activator is a solution of hydrogen peroxide (H2O2) and sodium hydroxide (NaOH) found in water. In the presence of iron, the hydrogen peroxide
