Why does the luminol light reaction stop after a period of time?
The luminol reaction is an example of "chemiluminescence". This is when a chemical reaction yields a product in an electronically excited state (at least one electron in the product is at a level above the ground state). The excited product loses energy in the form of a photon of light when the electron drops to the ground state level. In the case of luminol the reaction is an oxidation under alkaline conditions and the reaction stops when either all the luminol, all the oxidising agent or all the alkali has been converted
The forensic technician at a crime scene has just prepared a luminol stock solution by adding 17.0 of luminol into a total volume of 75.0 of?
.110 M
What chemical can be used to detect blood when been wiped from a surface?
luminol
What is a chemical reaction producing heat and light?
Any chemical will give off light if it is heated to a sufficiently high temperature. There are also chemicals that give off light at relatively low temperatures. Fireflys produce a type of chemical called luciferins, that produce light.
What type of evidence are fingerprints and footprints?
I don't think evidence is categorized... But..It would depend: if it is a hidden print, it will probably have to be discovered using some kind of chemicals such as luminol or simple things like powder, this meaning it will require forensics. So pretty much: 'Forensic evidence', But if it had nothing to do with discovering it using forensics, well, someone else will have to answer that for you.Added: It is known as PHYSICAL EVIDENCE.
What is luminol used for in crime scenes?
The basic idea of luminol is to reveal blood traces with a light producing chemical reaction between several chemicals and hemoglobin.

What are the chemicals in a glow stick?
could be all sorts, but the basics are luminol and sodium hydroxide When they react, light is given out.
What is a Chemical light?
You are probably thinking of chemiluminescence. This occurs during a chemical reaction when light is emitted. Search luminol.
Why should a positive result from luminol test not be taken as proof of the presence of the blood?
Luminul also reacts with certain kinds of chemicals, like bleach rv
What is an episode from CSI that uses luminol?
Luminol is used in most episodes of CSI as it detects the presence of blood.
How does temperature in a luminol reaction affect light produced?
If the temperature of the glow stick (chemiluminescence) is warmer, it releases a brighter glow and has a shorter reaction time. If the temperature of the glow stick is colder, it releases a dimmer glow but has a longer reaction time. Lower temperatures slow reaction rates and release less light intensity then higher temperatures.
What are two examples of tests that can be done to detect blood at a crime scene?
Forensic scientists test blood at a crime scene using the chemicals Luminol (C8H7N3O2) and hydrogen Peroxide (H2O2). if blood is present when they use these chemicals, it will glow with a bluish color in the dark. I hope this helps.
How does temperature affect luminol at a crime scene?
If the temperature is cold then the luminol will have a brighter excited state than if the temperature was hot or room temp.
What is the biggest chemical reaction from homemade stuff?
How big is the biggest chemical reaction depends on what you mean by "big." Is it a reaction with the most spectacular result, the most ingredients, the most steps, or the most of something else? One suggestion was making Luminol, which is an 8 step reaction, and each step is a chemical reaction its self. Look at NurdRage video on how to make it on YouTube
What reacts with the blood to cause luminesce?
Luminol
