condition. In the case of liquid, ammonia-water mixtures, the heat of solution has been considered in computing the enthalpy values. In the case of the vapor mixtures the heat of mixing is considered zero. This is very closely true with vapors free from liquid. The datum for en­ thalpy computations was taken as 32" F. Thus enthalpy

Ammonia - Thermophysical Properties

Ammonia is a colourless gas with a characteristic pungent smell and hazardous in its concentrated form.. Chemical, physical and thermal properties of Ammonia, NH 3: Values at 25 o C /77 o F / 298 K and 1 atm., if not other temperature and pressure given. If values are given for liquid ammonia at ambient temperature, the ammonia is pressurized above 1 atm.

Ammonia solution - Wikipedia

Ammonium hydroxide, also known as ammonia water, ammonia solution, ammoniacal 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). Although the name ammonium hydroxide suggests an alkali with composition [NH 4 +][OH −], it is actually impossible to isolate samples of NH 4 OH.
