BRAIN BOLT on Instagram: "When luminol is introduced into a 10% bleach solution, a striking blue glow appears instantly, and this reaction is one of the most famous demonstrations of chemiluminescence. Luminol is a chemical compound that emits light when it undergoes oxidation. In this case, the bleach provides sodium hypochlorite, a strong oxidizing agent, which reacts with luminol in the presence of a basic environment. As the luminol molecules are oxidized, they enter an excited energy state,
