Ammonium Sulfate CAS: 7783-20-2

Description

Pure ammonium sulfate is a white crystal, and it begins to decompose into ammonia and ammonium bisulfate when heated to 100° C. The by-product is slightly yellow or gray, has low hygroscopicity, and is not easy to agglomerate, so it is easier to store, and it is easier to dissolve in water and insoluble in ethanol and acetone.

Ammonium sulfate is a physiologically acidic quick-acting nitrogen fertilizer, which is generally suitable for wheat, corn, rice, cotton, sweet potato, hemp, fruit trees, vegetables and other crops. For soil, ammonium sulfate is most suitable for neutral and alkaline soils, but not for acidic soils. It is also used as analytical reagent (precipitant, masking agent), supporting electrolyte in electrochemical analysis, microbial culture medium and ammonium salt preparation.
