How does copper sulfate react with luminol
WebOther 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. WebNov 10, 2016 · 1. Set out the two clear plastic cups that came with the kit. 2. Add one scoop each of luminol and perborate mixtures and a few copper sulfate crystals to each cup. 3. Add 1/3 cup of ice-cold water to a styrofoam cup. 4. Add 1/3 cup of hot tap water (about 50°C) to a second styrofoam cup. 5.
