Colorless crystals or white granules. No smell. More than 280 ℃. Solubility in water: 41.22 g when 0 ℃, 25 ℃ at 43.47 g, 50.42 g 100 ℃. Insoluble in ethanol and acetone. 0.1 mol/L solution of pH 5.5. Relative density 1.77. The refractive index of 1.521. Low toxicity, median lethal dose (rats, through the mouth) 3000 mg/kg. Stimulating. Ammonium sulfate is mainly used as fertilizer, suitable for various soil and crop. Can also be used in textile, leather, medicine, etc.


Use:


A good nitrogen (commonly known as ammonium sulphate), suitable for general soil and crop, can make the branches and leaves growth, improve fruit quality and yield, enhance crops on disaster resistance ability, as a basic fertilizer, fertilizer and seed manure, but the long-term use can lead to soil harden. Has double decomposition reaction with salt to produce ammonium chloride and ammonium aluminum sulfate effect generated alum, manufacturing refractory materials with boric acid and so on. Join the plating solution can increase the conductivity. Food caramel catalyst, in the production of yeast cultivation nitrogen source of yeast, to dye and acid dyes leather dust remover. In addition, also used in beer brewing, chemical reagent and battery production, etc. Another important role is to mine rare earths, extraction with ammonium sulfate as raw material, adopts the ion exchange form of rare earth elements in the ore exchange, to collect leach liquor.
