ammoniumsoolad

Ammoniumsoolad, commonly known as ammonium sulfate, is a white, crystalline solid with the chemical formula (NH4)2SO4. It dissociates in water to yield ammonium and sulfate ions and is highly soluble in water. In aqueous solution, the salt forms an acidic solution due to the weakly acidic ammonium ions.

Industrial production of ammonium sulfate mainly involves the reaction of ammonia with sulfuric acid: 2 NH3 + H2SO4 → (NH4)2SO4. It is also obtained as a byproduct in certain chemical and polymer processes. The material is typically sold as a dry solid suitable for handling and storage.

Physically, ammonium sulfate is stable at ambient temperatures and exists as a crystalline solid. Its high solubility in water makes it useful for delivering nitrogen and sulfur to plants. The dissolution process in water is slightly endothermic, which can cause a modest cooling effect when the solid is added to hot water or concentrated solutions.

The primary use of ammonium sulfate is as a fertilizer. It provides available nitrogen and sulfur nutrients to crops and is valued for its ability to acidify soils, which can benefit acid-loving plants. Beyond agriculture, ammonium sulfate finds applications in certain fermentation processes and laboratory settings as a source of ammonium and as a buffering or salt-forming agent.

Safety and handling notes: ammonium sulfate is of low acute toxicity but can irritate the skin, eyes, and lungs if dust is inhaled or contact occurs. It should be stored in a dry, well-ventilated area in moisture-resistant containers away from incompatible substances. Environmental considerations include the potential for soil acidification and impacts on aquatic ecosystems if released in large quantities.
