Applications
Ammonium sulfate is widely utilized as a fertilizer for alkaline soils. In biochemistry it is used for purification of proteins via ammonium sulfate precipitation method. As a food additive, it serves as an acidity regulator in flours and breads. It is used in the preparation of other ammonium salts, particularly ammonium persulfate. It is applied in several applications as a flame retardant and a wood preservative. It finds use as raw materials for various chemical products such as dyes and pharmaceutical products. A saturated solution of ammonium sulfate in heavy water is employed as an external standard in sulfur-33 NMR spectroscopy.
Solubility
Soluble in water. Insoluble in alcohol and acetone.
Notes
Incompatible with various substances like highly reactive oxidizing agents and alkalis.
