I mix an amonia solution (30% or better), with copper oxide at around 40*c, add amonium nitrate, recrystalize, desolve in acetone and recristalize
again? (i amlost did this by accident and somehting tells me im lucky i didnt)bbartlog - 15-9-2011 at 02:17
I almost assembled a jigsaw puzzle by accident once. Anyway, this belongs in Beginnings. Or detritus (best choice). Or maybe energetic materials if
the moderators are feeling generous.blogfast25 - 15-9-2011 at 05:04

... is more orl less the right answer.
Strong ammonia will probably attack CuO (assuming it was cupric oxide) he was talking about),, forming some cupric ammonium complex (deep blue). With
ammonium nitrate and some crystallisation you might get some copper (II) nitrate ammoniacate. Not sure about the acetone.
Conducting experiments 'by accident' is rarely a good idea, although some have given interesting historical results...

Not true. Ammonia will turn cupric oxide into copper metal according to this reaction:
2 NH3 + 3 CuO = 3 Cu + 3 H2O + N2
Mixing copper with ammonium nitrate and some heating what he will probably get is some copper nitrate(not sure about that).

copper(II) oxide only oxidizes NH3 when heated; simply reacting NH4OH with CuO does not liberate any N2.
one should be very cautious about heating copper with NH4NO3.
"copper, iron, lead, magnesium, manganese, nickel, tin, and zinc reacted violently or explosively with fused ammonium nitrate below 200C."
