For professionals in the chemical industry, a thorough understanding of a compound's properties is crucial for its effective and safe application. Ferrous Sulfate Heptahydrate (CAS 7782-63-0), a widely used industrial chemical, exhibits specific characteristics that dictate its utility and handling. As an experienced chemical manufacturer, we aim to provide insight into these essential aspects.

Ferrous Sulfate Heptahydrate typically appears as green, monoclinic crystals or powder. It has a relative density of approximately 1.898 and a melting point around 64°C. A key property is its high solubility in water, with solubility increasing with temperature. For instance, at 50°C, it dissolves readily at 48.6g/100ml of water. In dry air, it can effloresce (weather), indicating a tendency to lose its water of crystallization. This hygroscopic nature means proper storage in well-sealed containers is essential.

The thermal behavior of Ferrous Sulfate Heptahydrate is also noteworthy. Upon heating, it undergoes dehydration. At 56.6°C, it transforms into tetrachydrates, and at 64.6°C, it becomes monohydrate. Complete dehydration to anhydrous ferrous sulfate occurs at around 300°C. At higher temperatures, it decomposes, releasing sulfur dioxide (SO2) and sulfur trioxide (SO3) gases, along with iron(III) oxide. This decomposition highlights the need for controlled heating environments when using this chemical.

Understanding these chemical behaviors allows for optimized use in various applications, from water treatment to agriculture.
