Beschreibung

§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.

Chemische Eigenschaften

light blue or light blue-green solid

Verwenden

Used in quantitative analysis of nitrates .

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).

Allgemeine Beschreibung

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 Reaktionen

Water soluble

Reaktivit?t anzeigen

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.

Sicherheitsprofil

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.

m?gliche Exposition

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.

l?uterung methode

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).

Inkompatibilit?ten

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.
