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.
One such form is ammonia (NH3). Ammonia may be taken up by plants or oxidized by bacteria into nitrate (NO3-) or nitrite (NO2). Ammonia (NH3+) is a colorless gas with a strong pungent odor. Ammonia will react with water to form a weak base. The term ammonia refers to two chemical species which are in equilibrium in water (NH3, un-ionized and NH4+, ionized). Tests for ammonia usually measure total ammonia (NH3 plus NH4+).
