In this how to video, you will learn about Chemiluminescence and the oxidation of Luminol. The first solution is Luminol and NaOH. The second is K3 and H202. Luminol is used to detect blood in crime scenes. It reacts with Iron in Hemoglobin. As you can see in the example, it illuminates the chemicals in the dark. This is why it is very useful for crime scenes. It can be used even if the blood is not visible with day light. Thus, it is an invaluable chemical in the name of science and justice. This video shows how Luminol is useful for its Chemiluminscence.
