Description

Ammonium Sulfate is an inorganic compound made by neutralization reaction of ammonia and sulfuric acid. Its chemical formula is (NH4)2SO4, and its molecular weight is 132.14. At room temperature, ammonium sulfate is white to light yellow crystals, easily soluble in water, and its aqueous solution is acidic, insoluble in ethanol and acetone. Ammonium sulfate has stable chemical properties, but it decomposes at high temperatures to produce ammonia and ammonium bisulfate. As an important chemical raw material, ammonium sulfate is widely used in fertilizer production and is one of the main sources of nitrogen and sulfur for crop nutrients. In addition, it is also used in many industrial fields such as textiles, leather, and medicine. This product is a pure ammonium sulfate compound, suitable for various application scenarios that require ammonium sulfate as a raw material or additive.

Features
High density and stability
The density of Ammonium Sulfate at 25°C is 1.77g/mL. This high density property allows it to occupy a smaller volume during storage and transportation, improves logistics efficiency, and reduces the need for storage space. At the same time, its melting point is higher than 280°C (decomposition), indicating that the substance has extremely high stability at room temperature and is not prone to thermal decomposition, thus ensuring the safety and reliability of the product during use.

Good water solubility
The water solubility of ammonium sulfate at 25°C is 77g/100 mL, which means that it can be easily dissolved in water to form a clear, colorless solution. This feature makes the application of ammonium sulfate in agriculture, chemical industry and other fields very convenient, and it can be quickly prepared into a solution of the required concentration for fertilization, chemical production and other purposes.

Low vapor pressure and environmental protection
The vapor pressure of ammonium sulfate at 25°C is less than 1Pa, which means that it is almost non-volatile at room temperature, thereby reducing the pollution to the environment during use. Low vapor pressure also means that ammonium sulfate is not easy to volatilize and lose during storage, maintaining the stability and durability of the product.

Moderate pH value and wide application
The pH value of ammonium sulfate in aqueous solution is 5.0-6.0 (25°C, 1M). This moderate pH value enables ammonium sulfate to maintain stable performance in a variety of application environments. Whether in an acidic or alkaline environment, ammonium sulfate can play its due role and will not fail due to changes in pH. This feature makes ammonium sulfate widely used in many fields such as agriculture, chemical industry, and textiles.
