Ammonium Sulphate

Agriculture:

• Fertilizer: Ammonium sulfate is primarily used as a fertilizer due to its high nitrogen content (approximately 21% nitrogen) and sulfur content (around 24% sulfur). It provides essential nutrients for plant growth and is especially useful in soils where these nutrients are deficient.
• Soil Amendment: It can help to improve soil fertility and correct sulfur deficiencies, which are important for protein synthesis in plants.

Industrial Uses:

• Water Treatment: Used in water treatment processes to remove impurities and help in the coagulation of particles.
• Chemical Production: Serves as a raw material in the manufacture of other chemicals, such as ammonium chloride and other ammonium salts.
• Textile Industry: Used in the dyeing process to fix dyes to fabrics and as a mordant.

Laboratory Uses:

• Protein Purification: In biochemistry, ammonium sulfate is used in a process known as "salting out" to precipitate proteins from solution. This technique is employed to purify proteins based on their solubility in salt solutions.

Food Industry:

• Additive: It is used as a food additive in some baking powders and as a dough conditioner.
