Ammonium Iron(II) Sulfate Hexahydrate (Mohr's Salt), ACS
Ammonium ferrous sulfate hexahydrate; Ferrous ammonium sulfate hexahydrate; Mohr's Salt

Ammonium iron(II) sulfate hexahydrate, commonly known as Mohr's salt, is a versatile compound widely used in various industrial and research applications. This double salt, composed of ammonium sulfate and iron(II) sulfate, is particularly valued for its stability and solubility in water. It serves as an important reagent in analytical chemistry, especially in redox titrations, where it acts as a primary standard for the determination of oxidizing agents. Additionally, its unique properties make it suitable for use in the preparation of iron-based catalysts and in the synthesis of other iron compounds.

In agriculture, ammonium iron(II) sulfate hexahydrate is utilized as a micronutrient fertilizer, providing essential iron to plants, which is crucial for chlorophyll synthesis and overall plant health. Its application extends to water treatment processes, where it aids in the removal of impurities and enhances water quality.
