When sodium hypochlorite (bleach) solution is added to luminol, a chemical reaction occurs that releases energy in the form of light. This is called chemiluminescence. The bleach solution acts as an oxidizing agent, which means it takes electrons away from the luminol molecule. This causes the luminol molecule to become excited, and it releases the energy as light.

The luminol molecule is made up of two amino groups, a carbonyl group, and an azo group. The amino groups are electron-rich, while the carbonyl group is electron-poor. The azo group is a conjugated system, which means that the electrons in the double bonds can move freely from one atom to another.
When sodium hypochlorite (bleach) solution is added to luminol, the bleach molecules react with the amino groups of the luminol molecule. This reaction takes electrons away from the luminol molecule, which causes the luminol molecule to become oxidized. The oxidized luminol molecule is in an excited state, which means that it has more energy than it normally does.
The excited luminol molecule then releases the extra energy as light. This light is called chemiluminescence. The light emitted by the chemiluminescence reaction is blue because the luminol molecule has a blue fluorescence.
The chemiluminescence reaction between luminol and sodium hypochlorite is catalyzed by the presence of a metal ion, such as iron or copper. The metal ion helps to stabilize the excited state of the luminol molecule, which makes it more likely to release the extra energy as light.
The chemiluminescence reaction is very sensitive to impurities, so it is important to use pure chemicals. The reaction can also be affected by the pH of the solution. The optimal pH for the reaction is around 9.
The chemiluminescence reaction between luminol and sodium hypochlorite can be used to detect blood, as the iron in hemoglobin can catalyze the reaction. The reaction is also used in some commercial products, such as glow sticks and emergency lights.
I hope you enjoyed learning about this. ❤️🙏

Tom Thibodeau’s debut on ESPN gave us THIS smile. Help.
The internet had a field day.
Tom Thibodeau made his broadcasting debut on ESPN Wednesday night and it went, well.

I love this. I love is so damn much it’s scary. I love it because on the first day of a job you pretty much have one job, and that’s to not look creepy. Thibs failed spectacularly with his frozen smile, unblinking stare and lack of awareness that he was on TV.
Naturally the Internet fell in love with the awkwardness, and the results were magical — so now I give you ...
18 things Tom Thibodeau looked like during his awkward, frozen smile.

I think he looks a little more like The Joker, though.
