Hi, needing help with something, I hope somebody help
Well, last week I had a laboratory and the subject was the one written on the title. The sample we used was ammonium iron (III) sulfate dodecahydrate and I need the dissociation of this salt with acid nitric, or dissociations to form ferric ion and I don't know how to do it, may someone want to help me? Please!

As of thermal decomposition you need to write the possible mechanism, like - Fe

O
3
, N
2
O, H
2
O and SO

as a products, and compare it to obtained graph (you need to coapt type of products to the graph).
