Luminol chemiluminescence?

Post  sinclairi18 on Mon May 28, 2012 7:08 pm

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 for your time
