Iron sulfate

Description : Scientific name: Iron sulfate with FeSO4 chemical formula

Other name: Green vitriol, plant and soil vitamin

Iron sulfate is a compound with FeSO4.7H2O formula that depending to it`s PH, can be produced in shape of blue or green crystals. In normal condition, there is 7 water molecules in the Iron sulfate combination and if dried, it will lose 6 molecules and change into a white mono hydrate powder.

Iron sulfate is from the raw materials of producing Chemical fertilizers. The amount of Iron sulfate is different in cereals and fruit trees according to crop type and soil type. For example, for Pistachio trees are in the areas of salt marsh, it has the most amount.

The uses of iron sulfate:

- production of fertilizers

- Agricultural micronutrients

- Farmland and orchards.

The chemical analysis of iron sulfate:

Industrially, ferrous sulfate is mainly used as a precursor to other iron compounds. It is a reducing agent, mostly for the reduction of chromate in cement. The term copperas refers to the historical use of ferrous sulfate as a chemical in the textile industry from the 17th century when it was used as a textile dye fixative, as a mean to blacken leather and also as a constituent of ink

Together with other iron compounds, ferrous sulfate is used to fortify foods and to treat iron deficiency anemia. Constipation is a frequent and uncomfortable side effect associated with the administration of oral iron supplements.


Ferrous sulfate was used in the manufacture of inks, most notably iron gall ink, which was used from the middle ages until the end of the eighteenth century. Chemical tests made on the Lachish letters [circa 588/6 BCE] showed the possible presence of iron (Torczyner, Lachish Letters, pp. 188–95). It is thought that oak galls and copperas may have been used in making the ink on those letters.[16] It also finds use in wool dyeing as a mordant. Harewood, a material used in marquetry and parquetry since the 17th century, is also made using ferrous sulfate.
