Ammonium sulphate is a white odorless solid. Sinks and dissolves in water.
Ammonium sulphate is an inorganic sulphate salt obtained by reaction of sulfuric acid with two equivalents of ammonia.
A high-melting (decomposes above 280℃) white solid which is very soluble in water (70.6 g/100 g water at 0℃; 103.8 g/100 g water at 100℃), Ammonium sulphate is widely used as a fertilizer for alkaline soils.
Ammonium sulphate has a role as a fertilizer.
Ammonium sulphate is an ammonium salt and an inorganic sulphate salt.
Ammonium sulphate (American English and international scientific usage; ammonium sulphate in British English); (NH4)2SO4, is an inorganic salt with a number of commercial uses.
The most common use is as a soil fertilizer.
Ammonium sulphate contains 21% nitrogen and 24% sulfur.
The primary use of ammonium sulphate is as a fertilizer for alkaline soils.
In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth.
The main disadvantage to the use of ammonium sulphate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs.
Ammonium sulphate is also used as an agricultural spray adjuvant for water-soluble insecticides, herbicides, and fungicides.
Ammonium sulphatet functions to bind iron and calcium cations that are present in both well water and plant cells.
Ammonium sulphate is particularly effective as an adjuvant for 2,4-D (amine), glyphosate, and glufosinate herbicides.
Ammonium sulphate precipitation is a common method for protein purification by precipitation.
As the ionic strength of a solution increases, the solubility of proteins in that solution decreases.
Ammonium sulphate is extremely soluble in water due to its ionic nature, therefore it can "salt out" proteins by precipitation.
Due to the high dielectric constant of water, the dissociated salt ions being cationic ammonium and anionic sulphate are readily solvated within hydration shells of water molecules.
The significance of Ammonium sulphate in the purification of compounds stems from its ability to become more so hydrated compared to relatively more nonpolar molecules and so the desirable nonpolar molecules coalesce and precipitate out of the solution in a concentrated form.
This method is called salting out and necessitates the use of high salt concentrations that can reliably dissolve in the aqueous mixture.
The percentage of the salt used is in comparison to the maximal concentration of the salt in the mixture can dissolve.
As such, although high concentrations are needed for the method to work adding an abundance of the salt, over 100%, can also oversaturate the solution, therefore, contaminating the nonpolar precipitate with salt precipitate.
A high salt concentration, which can be achieved by adding or increasing the concentration of ammonium sulphate in a solution, enables protein separation based on a decrease in protein solubility; this separation may be achieved by centrifugation.
Precipitation by ammonium sulphate is a result of a reduction in solubility rather than protein denaturation, thus the precipitated protein can be solubilized through the use of standard buffers.
Ammonium sulphate precipitation provides a convenient and simple means to fractionate complex protein mixtures.
In the analysis of rubber lattices, volatile fatty acids are analyzed by precipitating rubber with a 35% ammonium sulphate solution, which leaves a clear liquid from which volatile fatty acids are regenerated with sulfuric acid and then distilled with steam.
Selective precipitation with ammonium sulphate, opposite to the usual precipitation technique which uses acetic acid, does not interfere with the determination of volatile fatty acids.

Particulate ammonium sulphate is the air emission occurring in the largest amount from manufacture of this fertilizer.
Dryer exhaust is the primary source of the particulates, and emission rates are dependent on gas velocity and particle size distribution.
