Why Does Luminol Emit Different Colors in Chemiluminescence?

AI Thread Summary
Luminol emits different colors during chemiluminescence due to varying energy states in the reaction with hydrogen peroxide and a catalyst. Initially, a red glow is observed, which transitions to white and then blue light before fading. The red light is attributed to intermediate products formed during the reaction, while the blue light is the result of the final excited state of luminol. The chemical equation for the reaction is generally represented as luminol + hydrogen peroxide + catalyst → H2O + O2, although specifics may vary. Understanding these color changes enhances comprehension of the underlying chemical processes involved in chemiluminescence.

Hi! So I have a question. We're doing this lab in my ap chem class revolving around chemiluminescence. In the lab, we mix luminol with hydrogen peroxide and a few other chemicals. Aftwerwards, we turn off the lights and the reactions proceeds to emit a red glow which then turns white and finally blue before fading away. I understand that the combination of the luminol and hydrogen peroxide cause the blue light to be emitted but what I don't under stand is what caused the red light to be emitted and how. Can anyone please help?

Also if anyone knows the chemical equation involved in this reaction that would be very helpful (I pretty sure it should be luminol + hydrogen peroxide + catalyst (formalyhydride) --> H2O + O2 + but correct me if I'm wrong)

Thank you very much for your time.

Tell us the exact procedure please.
 
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
