Ammonium arsenate explained

Ammonium arsenate is the inorganic compound with the formula (NH4)3AsO4. It is prepared by treating a concentrated solution of arsenic acid with ammonia, resulting in precipitation of colorless crystals of the trihydrate.[1] Upon heating, it releases ammonia.

Like other compounds of arsenic, it is classified as an IARC Group 1 carcinogen, i.e. carcinogenic to humans.[2]

Acid salts are also known, including diammonium arsenate and ammonium dihydrogen arsenate.
