Read： 918 Time：18months ago Source：Transform the World with Simplicity

Ammonium sulfate, chemical formula (NH4)2SO4, is a common inorganic compound. It is a salt composed of ammonium ions (NH4) and sulfate ions (SO42-). Ammonium sulfate is a white powder, soluble in water, commonly used in agriculture, chemical industry, medicine and other fields. In this paper, the chemical formula of ammonium sulfate will be analyzed in detail. Composition of

Ammonium Sulfate
Brackets in the chemical formula of
ammonium sulfate represent structural units. The left side of the bracket is the ammonium ion and the right side is the sulfate ion. The ammonium ion consists of a nitrogen atom and four hydrogen atoms, NH4. The sulfate ion consists of one sulfur atom and four oxygen atoms, SO42 −-. Thus, the chemical formula of ammonium sulfate can be expressed as (NH4)2SO4.

Since ammonium sulfate is composed of ammonium ions and sulfate ions, it is also a salt compound. A salt compound is a compound formed by combining an anion, a cation, or a positive ion and a negative ion in a molecule or a molecule. The cation of ammonium sulfate is an ammonium ion and the anion is a sulfate ion.

the physical properties of ammonium sulfate

ammonium sulfate is a white crystal or powder, with good solubility and stability. Its solubility in water increases with increasing temperature. At 20°C, 70 grams of ammonium sulfate can be dissolved per 100 grams of water. At high temperatures, ammonium sulfate decomposes to release the toxic gases ammonia (NH3) and sulfur dioxide (SO2).
the chemical properties of
ammonium sulfate
the chemical formula of
ammonium sulfate contains nitrogen atoms and sulfur atoms, so it has some special chemical properties. The most common reaction is hydrolysis. The hydrolysis reaction refers to the reaction in which ammonium sulfate is decomposed into ammonium ion and sulfate ion in water, as follows:

(NH4)2SO4 + H2O → 2NH4 + SO42-

The hydrolysis reaction is one of the main reactions of ammonium sulfate in water. It is also one of the main applications of ammonium sulfate in agriculture and medicine.
Application of
Ammonium Sulfate

Ammonium sulfate is a widely used chemical. Its main application areas include:

1. Fertilizer: Ammonium sulfate is a common nitrogen fertilizer in agriculture. It can provide nitrogen to crops and promote the growth and development of plants.

2. fireworks: ammonium sulfate is a commonly used basic fireworks chemicals. It can promote the burning and color change of fireworks.

3. Medicine: Ammonium sulfate is also widely used in medicine, for example, for the treatment of hepatitis, rheumatism and arthritis and other diseases.
