황산 암모늄 제1철 C화학적 특성, 용도, 생산

화학적 성질

Ferrous ammonium sulfate is a pale green or blue-green solid (powder or lumpy crystals).

물리적 성질

Bluish-green monoclinic crystal; density 1.86 g/cm3; deomposes at 100°C;soluble in water; insoluble in alcohol.

용도

Iron ammonium sulfate is an analytical reagent in titrations and colori-metric measurements to measure oxidizing substances, such as chlorine, or tomeasure the chemical oxygen demand in waste water. The compound is usedto prepare Fe(II) standard solution for these analyses. It also is a calibration standard in magnetic measurements; a reducing agent; a catalyst for poly-merization; and is used in photographic chemistry.

제조 방법

Ferrous ammonium sulfate may be prepared by mixing an equimolar solution of ferrous sulfate and ammonium sulfate, followed by evaporation andcrystallization.

정의

ChEBI: A compound of ammonium, iron and sulfate in which the ratio of ammonium to iron(2+) to sulfate ions is 2:1:2.

일반 설명

A light green crystalline solid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Ammonium iron(II) sulfate is used in medicine, chemical analysis and metallurgy.

공기와 물의 반응

Soluble in water that forms weakly acidic solutions. Deliquesces in air.

반응 프로필

Ammonium iron(II) sulfate is a weak reducing agent. Irritating and toxic ammonia and oxides of nitrogen may form in fires [USCG, 1999].

건강위험

Inhalation of dust irritates nose and throat. Ingestion causes irritation of mouth and stomach. Dust irritates eyes and can irritate skin on prolonged contact.

화재위험

Special Hazards of Combustion Products: Irritating and toxic ammonia and oxides of nitrogen may form in fires.

잠재적 노출

This substance is used in photography, analytical chemistry and in dosimeters.

Purification Methods

A solution in warm water (0.67g/mL) is cooled rapidly to 0o, and the resulting light bluish-green monoclinic crystals are filtered at the pump, washed with cold distilled water and pressed between sheets of filter paper to dry it. The solubility at 25o is 0.36g/mL. It separates as an almost white powder when a saturated aqueous solution is diluted with EtOH.
