This page provides supplementary chemical data on ammonia. Structure and properties ... log 10 of anydrous ammonia vapor pressure. Uses formula shown below.
The rate constant, k, of this reaction depends on the temperature of the environment, with a value of at 10 K. [179] The rate constant was calculated from the formula = (/) . For the primary formation reaction, a = 1.05 × 10 −6 and B = −0.47 .
In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium: . NH 3 + H 2 O ⇌ NH + 4 + OH −.. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH +
In chemistry and physics, the dimensionless mixing ratio is the abundance of one component of a mixture relative to that of all other components. The term can refer either to mole ratio (see concentration ) or mass ratio (see stoichiometry ).

Ammonium bifluoride is an inorganic compound with the formula [NH 4][HF 2] or [NH 4]F·HF. It is produced from ammonia and hydrogen fluoride . This colourless salt is a glass- etchant and an intermediate in a once-contemplated route to hydrofluoric acid .
The truck was carrying about 7,500 gallons of anhydrous ammonia at the time, according to the Illinois Environmental Protection Agency. The agency said early estimates indicate more than half ...
