ammonia
Ammonia is a colorless gas with a sharp, pungent odor. Smelling salts utilize this powerful odor. Gaseous ammonia readily liquefies to give a colorless liquid that boils at 33 C. Due to intermolecular hydrogen bonding, the enthalpy of vaporization of liquid ammonia is higher than that of any other liquid except water, so ammonia is useful as a refrigerant. Ammonia is quite soluble in water 658 L at STP dissolves in 1 L H2O . The chemical properties of ammonia are as follows: 1. Ammonia acts as a Brnsted base, as discussed in the chapter on acid-base chemistry. The ammonium ion is.
