Ammonium Sulphate Properties

Ammonium Sulphate

Molecule Structure Image



Ammonium sulphate is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen as ammonium cations, and 24% sulfur as sulfate anions. In fertilizer the purpose of the sulfate is to reduce the soil pH.It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides.It is also used in the preparation of other ammonium salts.In biochemistry, ammonium sulfate precipitation is a common method for purifying proteins by precipitation.Ammonium sulphate is also a food additive.It has also been used in flame retardant compositions acting much like Diammonium phosphate. As a flame retardant, it lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an i
