Ferrous sulfate (FeSO4), is an important chemical, has a wide range of applications. This paper will analyze its nature, use, upstream and downstream raw materials and storage methods in detail.

1. Properties and Chemical Structure

Ferrous sulfate has the chemical formula FeSO4 and is usually present in solid or crystalline form. Its properties include:

Physical: Common colorless or light green crystal, soluble in water.
Chemical: in the air easily oxidized to ferric sulfate, with a certain degree of reduction.

2. Main purpose and application field

Ferrous sulfate has important uses in a number of areas, including but not limited:

Agriculture: as a soil conditioner and plant nutritional supplement, especially in iron-deficient areas.
Water treatment: used as a copper removal agent, phosphorus removal agent and chloride precipitation agent.
Medicine: As an iron supplement, used to treat iron deficiency anemia.
Industrial: used to prepare other iron salts, dye intermediates and iron oxidizing agents.

3. Upstream raw material analysis

The production of ferrous sulfate involves the following main raw materials:

Iron ore: common is iron containing higher ore, such as hematite.
Sulfuric acid: As a reaction reagent, used to produce ferrous sulfate.
Water: as a reaction solvent and crystallization process medium.

4. Downstream products and market applications

As an intermediate, ferrous sulfate can be used to prepare a variety of products, such:

Ferric sulfate: through the oxidation of ferrous sulfate, widely used in water treatment and agriculture.
Iron oxidant: used in industrial oxidation reaction and dye intermediate preparation.

5. Storage methods and considerations

In order to ensure the stability and safety of ferrous sulfate, the following storage methods should be paid attention:

Moisture: Avoid exposure to humid environments to prevent crystallization or deterioration.
Avoid light: should be stored in a cool, dry and ventilated place, away from direct sunlight.
Isolated: with oxidants and strong acid separately stored to avoid chemical reactions.

Conclusion

As a multifunctional chemical, ferrous sulfate is stable in nature and widely used, covering many fields such as agriculture, industry and medicine. The correct storage and use methods are essential to ensure product quality and safety, and it is necessary to strictly follow relevant operating procedures in actual production and application.
