ammonium perchlorate
Ammonium Chloride
NH4Cl is ammonium chloride.
Ammonium Dichromate: (NH4)2Cr2O7. The subscript on Ammonium (NH4) is 2.
ammonium tetraoxosulphate vi acid *************************** We were taught this is Ammonium Hydrogen Sulphate [Also: Ammonium Bisulphate]
The subscript for ammonium in ammonium dichromate is (NH4)2. This means there are two ammonium ions present in the compound.
Ammonium ion (NH4+) is present in all ammonium salts (eg. ammonium chloride, or ammonium nitrate), and in smaller amounts in an ammonia (NH3) solution.
