Ferrous ammonium sulfate

Description:
Ferrous ammonium sulfate, also known as ammonium iron(II) sulfate or Mohr's salt, is an inorganic compound with the formula (NH4)2Fe(SO4)2·6H2O. It typically appears as a greenish crystalline solid and is highly soluble in water. This compound is characterized by its ability to act as a source of ferrous ions (Fe²⁺) in various chemical reactions, making it useful in analytical chemistry, particularly in redox titrations. Ferrous ammonium sulfate is often employed as a reducing agent and is also utilized in the preparation of other iron compounds. It is stable under normal conditions but can oxidize to ferric compounds when exposed to air. Additionally, it is hygroscopic, meaning it can absorb moisture from the environment. In terms of safety, it is generally considered to have low toxicity, but precautions should be taken to avoid ingestion or inhalation of dust. Overall, ferrous ammonium sulfate is a versatile compound with significant applications in both laboratory and industrial settings.
