FERROUS SULFATE Chemical Properties,Uses,Production
- Nutritional supplements (iron enhancer); color former of fruit and vegetable; for example, the salted product used together with dried alum in eggplant can form stable complex salt with its pigment to prevent the discoloration caused by organic acids. However, it should be noted, for example, it will turn into black ink upon excess amount of iron. When the amount of alum is high, the meat of the pickled eggplant meat will become excessively solid. Formulation example: long eggplant 300 kg; edible salt 40kg; ferrous sulfate 100g; dried alum 500g. It can still be used as the color forming agent of black beans, sugar boiled beans and kelp. Food containing tannins, in order to avoid of causing blackening, should not be used. It can also be used for sterilization, deodorization and very weakly bactericidal.
- Legumes contained cryptochromic pigment is colorless upon reduction state while being oxidized into black upon oxidation in alkaline condition. Taking advantage of the reduction property of ferrous sulfate can achieve the purpose of color protection with the usage amount of 0.02% to 0.03%.
- If is used for the manufacturing of iron salt, iron oxide pigments, mordant, purifying agent, preservatives, disinfectants and medicine for anti-anemia drugs

Chemical PropertiesGreenish or yellow-brown crystals or granules; odorless. Soluble in water with saline taste; insoluble in alcohol. hygroscopic.
Chemical PropertiesFerrous sulfate is a greenish or yellowish solid in fine or lumpy crystals.
UsesFerrous Sulfate is a nutrient and dietary supplement that is a source of iron. it is a white to grayish odorless powder. ferrous sulfate hep- tahydrate contains approximately 20% iron, while ferrous sulfate dried contains approximately 32% iron. it dissolves slowly in water and has high bioavailability. it can cause discoloration and rancidity. it is used for fortification of baking mixes. in the encapsulated form it does not react with lipids in cereal flours. it is used in infant foods, cereals, and pasta products.
UsesFerrous sulfate (FeSO4) is also known as iron sulfate or iron vitriol. It is used in the production of various chemicals, such as sulfur dioxide and sulfuric acid.
DefinitionA rusty-brown solid prepared by the action of heat on iron(III) hydroxide or iron(II) sulfate. It occurs in nature as the mineral hematite. Industrially it is obtained by roasting iron pyrites. Iron(III) oxide dissolves in dilute acids to produce solutions of iron(III) salts. It is stable at red heat, decomposes around 1300°C to give triiron tetroxide, and can be reduced to iron by hydrogen at 1000°C. Iron(III) oxide is not ionic in character but has a structure similar to that of aluminum(III) oxide.
DefinitionCopperas: an off-whitesolid, FeSO4.H2O; monoclinic; r.d.2.970. There is also a heptahydrate,FeSO4.7H2O; blue-green monoclinic;r.d. 1.898; m.p. 64°C. The heptahydrateis the best known iron(II) saltand is sometimes called green vitriolor copperas. It is obtained by the actionof dilute sulphuric acid on ironin a reducing atmosphere. The anhydrouscompound is very hygroscopic.It decomposes at red heat to giveiron(III) oxide, sulphur trioxide, andsulphur dioxide. A solution of iron(II)sulphate is gradually oxidized on exposureto air, a basic iron(III) sulphatebeing deposited.
HazardIngestion causes intestinal disorders.
Agricultural UsesCopperas, also called green vitriol, is ferrous sulphate heptahydrate. It is an iron salt fertilizer, which is most effective in overcoming iron deficiency.
Agricultural UsesFerrous sulphate heptahydrate (FeSO4.7H2O), also called green vitriol or copperas, is a blue-green water-soluble crystal and is the best known ferrous salt. It is obtained by the action of dilute sulphuric acid on iron in a reducing atmosphere. The anhydrous compound is very hygroscopic. It gets oxidized gradually in an aqueous solution. On heating, the solid decomposes to give red ferric oxide, sulphur trioxide (SO3) and sulphur dioxide (SO2).
Safety ProfileA human poison by ingestion. Moderately toxic to humans by an unspecified route. An experimental poison by ingestion, intraduodenal, intraperitoneal, intravenous, and subcutaneous routes. Human systemic effects by ingestion: aggression, somnolence, brain recorlng changes, diarrhea, nausea or vomiting, bleedmg from the stomach, coma. Questionable carcinogen with experimental tumorigenic data. Experimental teratogenic and reproductive effects. Mutation data reported. Potentially explosive reaction with methyl isocyanoacetate at 25'. May igmte on contact with arsenic trioxide + sodium nitrate. When heated to decomposition it emits toxic fumes of SOx. See also IRON COMPOUNDS.
Potential ExposureIt is used as a fertilizer, food or feed additive; and in herbicides; process engraving; dyeing, and water treatment. A byproduct of various chemical and metal treating operations.
Veterinary Drugs and TreatmentsWhile iron is a necessary trace element in all hemoglobin-utilizing animals, the use of therapeutic dosages of ferrous sulfate (or other oral iron) preparations in veterinary medicine is limited primarily to the treatment of iron-deficiency anemias in dogs (usually due to chronic blood loss), and as adjunctive therapy in cats when receiving epoetin (erythropoietin) therapy. Injectable iron products are usually used in the treatment of iron deficiency anemias associated with newborn animals.
IncompatibilitiesAqueous solution is acidic. Contact with alkalies form iron. Keep away from alkalies, soluble carbo nates; gold and silver salts; lead acetate; lime water, potassium iodide; potassium and sodium tartrate; sodium borate; tannin.
