How to make Chromium(IV) triamine diperoxide
NOTE: In the chemical equation for the reaction, I use "K." I meant to say "NH4," meaning ammonium. NOTE: There has been some questioning of whether this compound is real. Chemistry of the Elements by N.N. Greenwood and A. Earnshaw states on page 1025 (in the 2nd and 3rd editions) that "[Cr(O2)2(NH3)3], which has a dark red-brown metallic lustre, may be obtained either by treating [Cr(O2)4]3- with warm aqueous ammonia or by the action of H2O2 on ammoniacal solutions of (NH4)2CrO4." I show you how to make Chromium (IV) triamine diperoxide, an explosive compound of chromium featuring chromium in the oxidation state 4+, a rare oxidation state. For more info on this interesting compound, see my chromium video: http://www.youtube.com/watch?v=edt4pnRqnfA&feature=plcp The inspiration for this experiment came from science made alive, a great website with nice chemistry experiments: http://woelen.homescience.net/science/index.html WARNING! This experiment uses ammonia, which can kill you if you inhale too much of the vapor. It also uses ammonium dichromate, which is an extremely flammable, carcinogenic compound - needless to say, goggles, a lab coat, and gloves are musts. 30% hydrogen peroxide can burn your skin. Wear splash goggles and gloves. The compound created is potentially carcinogenic, and quite flammable. When decomposing it, wear goggles, gloves, a lab coat, and a dust respirator, and perform the experiment outside or in a fume hood. DO NOT ATTEMPT THIS EXPERIMENT IF YOU DON'T KNOW HOW TO HANDLE THESE COMPOUNDS SAFELY!!!!
