  • Ammonia - McGill School Of Computer Science

    Ammonia is a compound of nitrogen and hydrogen with the formula NH 3.At standard temperature and pressure, ammonia is a gas.It is toxic and corrosive to some materials, and has a characteristic pungent odour. Ammonia used commercially can be anhydrous ammonia (not dissolved in water) or an aqueous solution of ammonia and water referred to as ammonium hydroxide.

  • ammonia | Definition & Uses | Britannica

    Ammonia readily dissolves in water with the liberation of heat. NH 3 + H 2 O ⇌ NH 4 + + OH − These aqueous solutions of ammonia are basic and are sometimes called solutions of ammonium hydroxide (NH 4 OH). The equilibrium, however, is such that a 1.0-molar solution of NH 3 provides only 4.2 millimoles of hydroxide ion.
