Ammonium dichromate volcano. Ammonium dichromate is the inorganic compound with the formula (NH4)2Cr2O7. It is a salt consisting of ammonium ions and dichromate ions. In the volcano demonstration,a pile of the salt is ignited,initiating an exothermic conversion. Its decomposition reaction proceeds to completion once initiated,producing voluminous dark green powdered chromium(III) oxide | |
