Ferrous Sulfate, also known as iron (II) sulfate, is an inorganic It is soluble in water, with the solution displaying a light green color. It is commonly encountered as the heptahydrate form known as green vitriol or copperas.
**Chemical Formula:** FeSO₄·7H₂O
**Appearance:** A blue-green crystalline solid.
**Uses:**
**Supplement:** Ferrous sulfate is commonly used as a dietary supplement to treat or prevent iron deficiency anemia. It provides a readily absorbable form of iron, which is essential for hemoglobin synthesis and oxygen transport in the body.
**Colorant:** In wastewater treatment plants to remove phosphates and heavy metals from effluent streams. It forms insoluble precipitates with phosphate ions and assists in metal ion removal through precipitation or coagulation.
**Analytical Chemistry:** Utilized in laboratory settings as a reducing agent and reagent in chemical analyses and experiments. It participates in redox reactions and is involved in the determination of substances such as sulfates, nitrates, and phenols.
