Iron (II) Sulfate is an inorganic compound with the chemical formula FeSO₄ and CAS Number 7720-78-7 for the anhydrous form. It is commonly supplied as a pale green to green crystalline solid, although its appearance may vary depending on the hydration form. Ferrous Sulfate Heptahydrate (FeSO₄·7H₂O) is another commonly available form with CAS Number 7782-63-0.

Iron (II) Sulfate is valued as a source of iron (II) ions in aqueous solutions and chemical reactions. Common laboratory applications include the preparation of iron-containing solutions, redox reactions, analytical chemistry procedures, iron determination, and inorganic chemistry experiments. It is also used in research involving oxidation-reduction processes and iron chemistry.

Its chemical reactivity and ability to provide ferrous ions make Iron (II) Sulfate useful in analytical chemistry, inorganic chemistry, environmental testing, and general laboratory research. It may also be used in specialised chemical formulations and water treatment applications. The appropriate grade, purity, and hydration form should be selected according to the requirements of the intended application.

KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.

Safety Note: Iron (II) Sulfate may cause irritation to the eyes, skin, and respiratory tract. Avoid inhalation of dust and direct contact with the chemical.
