Ammonia as Nitrogen. ALS Environmental may or may not test for Ammonia as Nitrogen (CAS # 7664-41-7). Information is subject to change; please contact us for the latest available analytes for which we test.
Ammonia solution, also known as ammonia water, ammonical liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). It is sometimes thought of as a solution of ammonium hydroxide. Although the name ammonium hydroxide suggests an alkali with composition [NH 4 +][OH â], it is actually impossible to isolate samples of NH 4 OH. The ions NH 4 + and OH â do not account for a significant fraction of the total amount of ammonia except in extremely dilute solutions.
