Question

Ammonium Sulphate oxidation number​

Answer 1

Answer:

Ammonium sulfate is an ionic compound, composed of two ammonium ions (NH4+NHX4X+) and one sulfate ion (SO42−SOX4X2−). As such, you can neglect the sulfate entirely from your consideration of the oxidation state of the nitrogen, as well as treating each ammonium ion as a separate entity. Given the total charge on the ammonium cation, it should be easy to see why the nitrogen has the specified oxidation state.
