Solubility in water (g/100mL)
Dissolved grams in 100 mL water at different temperatures (°C):
28.8g/0℃: 40g/10℃;48g/20℃;60g/30℃;73.3g/40℃
101g/60℃: 79.9g/70℃;68.3g/80℃;57.8g/90℃
Chemical properties
Blue-green crystals (monoclinic system) or granules, odorless. Soluble in water, slightly soluble in alcohol, soluble in anhydrous methanol.
Applications
As analytical reagent; as raw material for ferrite; raw material to produce magnetic iron oxide, iron(III) oxide and iron blue inorganic pigment, iron catalyst and poly iron sulfate; as chromatographic reagent. In agriculture, it is used as pesticide in agriculture to control wheat smut, scab of apple and bear, fruit tree decay; as fertilizer to remove moss and lichen of food trunk. Medically it is used as local astringent, blood tonic and anti-anemia. Ferrous sulfate heptahydrate (feed grade) can be used as the iron fortifier for feed additive. Ferrous sulfate heptahydrate (food grade) is used as nutrition supplements, such as iron fortifier, coloring agent for fruit and vegetable. According to Chinese regulation, it can be used in following foods and with allowed amounts:
Sweets with filling and salt: 3000~6000 mg/kg;
Cereals with high iron content and corresponding products (maximum daily consumption 50g): 860~960 mg/kg;
Dairy and infant foods: 300-500 mg/kg;
Cereals and corresponding products: 120~140 mg/kg;
Beverages: 50~100 mg/kg. It is used to produce iron salt, iron oxide pigment, mordant, water purifier, preservatives, disinfectant, etc.
Preparation
- By-product Method: byproduct of titanium dioxide production:
5H2SO4+2FeTiO3→2FeSO4+TiOS04+Ti(SO4)2+5H2O
- Sulfuric acid method
Fe+H2SO4→FeSO4+H2↑

Description
§184.1315(a) Ferrous sulfate heptahydrate (iron (II) sulfate heptahydrate, FeS04-7H2O) is prepared by the action of sulfuric acid on iron. It occurs as pale, blueish-green crystals or granules. Progressive heating of ferrous sulfate heptahydrate produces ferrous sulfate (dried). Ferrous sulfate (dried) consists primarily of ferrous sulfate monohydrate (CAS No. 17375-41-6) with varying amounts of ferrous sulfate tetrahydrate (CAS No. 20908-72-9) and occurs as a grayish-white to buff-colored powder.
Chemical Properties
Ferrous sulfate is a greenish or yellowish solid in fine or lumpy crystals.
Chemical Properties
light blue or light blue-green solid
Uses
Used in quantitative analysis of nitrates .
Uses
In manufacture of Fe, Fe Compounds, other sulfates; in Fe electroplating baths; in fertilizer; as food and feed supplement; in radiation dosimeters; as reducing agent in chemical processes; as wood preservative; as weed-killer; in prevention of chlorosis in plants; in other pesticides; in writing ink; in process engraving and lithography; as dye for leather; in etching aluminum; in water treatment; in qualitative analysis ("brown ring" test for nitrates); as polymerization catalyst.
Uses
Iron(II) sulfate heptahydrate is used as a precursor to prepare other iron compounds such as a lawn conditioner and a mordant for wool dyeing. It is actively used in the manufacture of ink including iron gall ink. As a reducing agent, it participates in the reduction of chromate in cement. It is also used in industrial water treatment plants to remove phosphate. It is also used in the gold refining process to precipitate metallic gold. Woodworkers use aqueous solutions of ferrous sulfate to color maple wood a silvery hue. It finds application in the treatment of iron chlorosis, which arises due to deficiency of iron in horticulture.
Definition
ChEBI: A hydrate that is the heptahydrate form of iron(2+) sulfate. It is used as a source of iron in the treatment of iron-deficiency anaemia (generally in liquid-dosage treatments; for solid-dosage treatments, the monohydrate is normally used).
General Description
A greenish or yellow-brown crystalline solid. Density 15.0 lb /gal. Melts at 64°C and loses the seven waters of hydration at 90°C. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Used for water or sewage treatment, as a fertilizer ingredient.
Air & Water Reactions
Water soluble
Reactivity Profile
Ferrous sulfate heptahydrate is a weak reducing agent.
Health Hazard
INGESTION: abdominal pain, retching, diarrhea, dehydration, shock, pallor, cyanosis, rapid or weak pulse, shallow respiration, low blood pressure.
Safety Profile
Poison by intravenous, intraperitoneal, and subcutaneous routes. Moderately toxic by ingestion and rectal routes. Mutation data reported. When heated to decomposition it emits toxic fumes of SOx.
Potential Exposure
It 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.
Purification Methods
Crystallise the sulfate from 0.4M H2SO4, or precipitate it from an aqueous solution with EtOH. It is efflorescent in dry air, and is converted to the tetrahydrate at 57o, then to the monohydrate at 65o (or by heating the heptahydrate in a vacuum at 140o). It forms a brown-black complex, FeSO4.NO, with nitric oxide and is used in a qualitative test for nitrates (“brown ring” test).
Incompatibilities
Aqueous 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.
