説明
§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.
化学的特性
light blue or light blue-green solid
使用
Used in quantitative analysis of nitrates .
定義
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).
一般的な説明
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.
空気と水の反応
Water soluble
反応プロフィール
Ferrous sulfate heptahydrate is a weak reducing agent.
健康ハザード
INGESTION: abdominal pain, retching, diarrhea, dehydration, shock, pallor, cyanosis, rapid or weak pulse, shallow respiration, low blood pressure.
安全性プロファイル
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.
職業ばく露
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.
純化方法
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).
不和合性
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.
