What is ammonia? Ammonia, also known as azane, is a chemical compound made of molecules which each contain one atom of nitrogen and three atoms of hydrogen. The molecular structure of ammonia is NH3. At ordinary room temperature and pressure, ammonia is a colourless gas which is lighter than air.
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.
