The Function and Purpose of Folding Editing this Paragraph

Ferrous sulfate can be used in iron salt, iron oxide pigments, mordants, water purifiers, preservatives, disinfectants, etc.

Chemical property

It is reducible. Toxic gases are released by high thermal decomposition. In the laboratory, it can be obtained by reacting copper sulfate solution with iron. Weathering occurs in dry air. It is easy to oxidize into brown-yellow basic ferric sulfate which is insoluble in water in moist air. 10% aqueous solution is acidic to litmus (Ph value is about 3.7). When heated to 70-73 ~C, 3 molecule water is lost, 6 molecule water is lost at 80-123 ~C, and converted to basic ferric sulfate above 156 ~C.


1. Water treatment


Ferrous sulfate is used to flocculate and purify water and remove phosphate from municipal and industrial wastewater to prevent eutrophication.


2. Reducing agent


A large amount of ferrous sulfate is used as reductant, mainly to reduce the chromite in cement.


3. Medicinal Use


Ferrous sulfate is used to treat iron deficiency anemia and to add iron to food. Long-term overuse may cause abdominal pain, nausea and other side effects.


It can also be used as a local astringent and blood tonic in medicine, and can be used for chronic bleeding caused by uterine leiomyoma.


4. Colorants


A. Ferrous sulfate is needed for the production of iron tannate ink and other inks. Ferrous sulfate is also contained in mordants for wood dyeing.


B. Ferrous sulfate can be used to dye concrete yellow rust.


C. Woodworking uses ferrous sulfate to dye Maple with silver.


5. Agriculture


Regulating soil acidity and alkalinity and promoting chlorophyll formation (also known as iron fertilizer) can prevent and cure yellow disease caused by iron deficiency of flowers and trees. It is an indispensable element of acid-loving flowers and trees, especially iron trees. Agricultural pesticides can also be used to control wheat smut, apple and pear scab, fruit tree rot; also can be used as fertilizer, can remove moss and lichen trunk.


6. Analytical Chemistry


Ferrous sulfate can be used as a reagent for chromatographic analysis.
