Ferrous ammonium sulfate hexahydrate

Description:
Ferrous ammonium sulfate hexahydrate, commonly known as Mohr's salt, is a coordination compound with the formula (NH4)2Fe(SO4)2·6H2O. It is characterized by its crystalline structure, typically appearing as greenish or yellow-green crystals. This compound is soluble in water, forming a pale green solution, and is stable under normal conditions. It is often used in analytical chemistry as a primary standard for redox titrations due to its ability to provide a reliable source of ferrous ions. The presence of both ammonium and ferrous ions contributes to its unique properties, including its ability to act as a reducing agent. Additionally, it is hygroscopic, meaning it can absorb moisture from the air, which is important to consider during storage. Ferrous ammonium sulfate hexahydrate is also utilized in various applications, including in the preparation of other iron compounds, as a fertilizer, and in the dyeing industry. Safety precautions should be taken when handling this compound, as it can cause irritation to the skin and eyes.
