Ammonium sulfate is colorless crystals or white particles. No smell. Decomposes above 280℃. Solubility in water: 70.6g at 0℃, 103.8g at 100℃. Insoluble in ethanol and acetone. The pH of 0.1 mol/L aqueous solution is 5.5. Relative density 1.77. Refractive index 1.521. Ammonium sulphate is mainly used as fertilizer and is suitable for various soils and crops. It can also be used in textiles, leather, medicine, etc. Function and Use 02 02 02 An excellent nitrogen fertilizer (commonly known as fertilizer field powder), which is suitable for general soil and crops. It can make foliage grow vigorously, improve fruit quality and yield, enhance crop resistance to disasters, and can be used as base fertilizer, top dressing and seed fertilizer. Ammonium chloride can be produced by metathesis reaction with table salt, ammonium alum is formed by action with aluminum sulfate, and refractories can be made with boric acid, etc. Adding it to the plating solution can increase the conductivity. It is also a catalyst for food paste color, a nitrogen source for cultivating yeast bacteria in fresh yeast production, an acid dye dyeing aid, and a leather deminerator. In addition, it is used in beer brewing, chemical reagents, and battery production. Another important role is the mining of rare earths. Ammonium sulfate is used as a raw material for mining, the rare earth elements in the ore are exchanged in the form of ion exchange, and then the leachate is collected to remove impurities, precipitate, press, and burn to form rare earth raw ore. About 5 tons of ammonium sulfate is required for each ton of rare earth raw ore mined and produced. 02 02 02 There are also many biological uses, mostly used in protein purification processes, because ammonium sulfate is an inert substance, it is not easy to react with other biologically active substances, and can protect protein activity to a greater extent during purification. In addition, ammonium sulfate is extremely soluble and can form a high-salt environment to prepare for protein precipitation and subsequent high-salt purification. The solubility of ammonium sulfate at zero degrees and 25 degrees at room temperature is very different. The following are the molar concentrations of ammonium sulfate with different saturation at two temperatures. 02 02 02 Ammonium sulfate, inorganic compound, pure product is colorless orthorhombic crystal, industrial product is white to light yellow crystal, easily soluble in water. Ammonium sulphate is mainly used as fertilizer and is suitable for various soils and crops. It can also be used in textiles, leather, medicine, etc.
