Ammonia Fireflies
(d) A spectacular demonstration of catalysis of the oxidation of ammonia by Chromium III oxide (which needs to be generted from the ammonium dichromate volcano. (H)
This demonstration reaction uses particles of chromium III oxide, generated from the ammonium dichromate volcano, to catalyse the reaction of ammonia vapour with oxygen – a reactions that proceeds in a shower of sparke – spectacular in a darkened room.
