After addition to soil, the ammonium sulfate rapidly dissolves into its ammonium and sulfate components. If it remains on the soil surface, the ammonium may be susceptible to gaseous loss in alkaline conditions. In these situations, agronomists advise incorporating the material into the soil as soon as possible.
Other options include an ammonium sulfate application before irrigation or a predicted rainfall. Most plants can utilize both ammonium and nitrate forms of N for growth. Ammonium sulfate has an acidifying effect on soil due to the nitrification process, not from the presence of sulfate, which has a negligible effect on pH. The acid-producing potential of ammonium sulfate is greater than the same N application from ammonium nitrate, for example, since all of the N in ammonium sulfate converts to nitrate, compared with only half of the N from ammonium nitrate that converts to nitrate.
Non-agricultural uses. What Is Ammonium Sulfate? The chemical compound ammonium sulfate is primarily used in fertilizers but is important in other industries as well. Ammonium sulfate, also called diammonium sulfate or sulfuric acid diammonium salt, is a white crystalline solid with no smell.
It tastes salty. The compound dissolves easily in water but will not dissolve in alcohol or acetone. When ammonium sulfate reacts with alkaline substances, it gives off ammonia gas. Ammonium sulfate is used most commonly as an artificial fertilizer for alkaline soils. In the laboratory, ammonium sulfate is made by reacting measured volumes of ammonia solution and sulfuric acid solution. A flow chart showing some of the stages in making ammonium sulfate Making ammonium sulfate in the laboratory In the laboratory, ammonium sulfate is made by reacting measured volumes of ammonia solution and sulfuric acid solution.
Two drops of methyl orange indicator are added. This will turn yellow in the alkaline ammonia solution. Dilute sulfuric acid is added from a burette slowly until the methyl orange indicator turns orange.
If too much acid is added it will turn red. The volume of sulfuric acid which has been added is recorded, and then the neutral solution of ammonium sulfate which contains the indicator is thrown away. Ammonium sulfate, NH 4 2 SO 4 , is a salt used as a fertiliser. It is a source of soluble nitrogen, so it can be used as a 'nitrogenous' fertiliser.
Ammonium sulfate can be made in the lab using dilute ammonia solution and dilute sulfuric acid:. Both reactants are soluble, so a titration must first be done to find the volumes of each reactant that exactly neutralise each other. Now that the reacting volumes are known, this is a method that can be used to make crystals of ammonium sulfate.
Eye protection must be worn.
