The topic is how temperature affects the glow of luminol when reacting with copper sulfate and perborate. The hypothesis is that if the temperature is high then the brighter the glow will be from the reaction. My reason for making that hypothesis is because temperature effects reactions which it is believed that the higher temperature will make it glow brighter. Other experiments mix luminol powder with hydrogen peroxide and hydroxide in bottles, and then sprayed on a drop of latent or dried blood. Some measure the time with the glow or make variation of the amount of copper sulfate crystals. They use 5, 10, and 15 copper grains, which prove that the more copper equals a faster reaction time. So with that information the experimental reactions shouldn’t be too fast to take photos of. Also there is an experiment with different oxidizers, like hydrogen peroxide, and bleach. This experiment, however, will include "Cool Blue Light Experiment Kit" which has the luminol, copper sulfate, and perborate. The experiment investigates the effects of temperature on the Chemiluminescence (cold light) reaction.…show more content… Luminol's chemical formula is C8H7N3O2 (3-Aminophthalhydrazide) and was first synthesized in 1853. Observed first by Albrecht in 1928 and then used as a forensic tool in 1937 by Specht and then again by Proesher and Moody in 1939. It is the most popular chemiluminescent compound, used by CSI teams to find trace amounts of blood at crime scenes. Blood will cause the reaction for ten years. The reaction lasts for about thirty seconds when in contact with dried blood. The reaction will be brighter and last longer with older blood. Another use of this experiment is when
