ferrosulfaatti

Ferrosulfaatti, also known as iron(II) sulfate, is an inorganic compound with the formula FeSO4. It is a chemical substance that can exist in hydrated forms, most commonly as the heptahydrate FeSO4·7H2O, which is a blue-green crystalline solid. Anhydrous ferrosulfaatti is a white solid, but it typically appears pale green due to the presence of small amounts of iron(III) impurities.

This compound has a variety of applications across different industries. In agriculture, it is used as a fertilizer to correct iron deficiency in soils, which can lead to chlorosis in plants. It also serves as a component in some herbicides and pesticides. In water treatment, ferrosulfaatti acts as a flocculant, helping to remove impurities and phosphates from wastewater.

Historically, ferrosulfaatti has been used in the production of inks, particularly iron gall ink, which was widely used for centuries. It also finds application in the dyeing of fabrics and in the medical field, where it is used as a supplement to treat iron deficiency anemia. Industrially, it is a precursor for the production of other iron compounds and is involved in pigment manufacturing. Ferrosulfaatti is soluble in water and reacts with bases.
