Talk:Ammonium arsenate

Formula

There are three different ammonium phosphates:

• Ammonium dihydrogenphosphate, [NH₄][H₂PO₄]
• Diammonium hydrogenphosphate, [NH₄]₂[HPO₄]
• Ammonium phosphate, [NH₄]₃[PO₄]

I searched a database of crystallographic databases (CrystalWeb) and found the following ammonium arsenates:

• Ammonium dihydrogenarsenate, [NH₄][H₂AsO₄]
• Diammonium hydrogenarsenate, [NH₄]₂[HAsO₄]
• Ammonium arsenate trihydrate, [NH₄]₃[AsO₄].3H₂O
