• Chemische Eigenschaften

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

• Physikalische Eigenschaften

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

• Verwenden

  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.

• synthetische

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

• Definition

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

• Allgemeine Beschreibung

  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.

• Air & Water Reaktionen

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

• Reaktivität anzeigen

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

• Health Hazard

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

• Brandgefahr

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

• Flammability and Explosibility

  Not classified

• mögliche Exposition

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

• Erste Hilfe

  If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seekmedical attention immediately. If this chemical contactsthe skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove fromexposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemical hasbeen swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.Note to physician: For severe poisoning do not use BAL[British Anti-Lewisite, dimercaprol, dithiopropanol(C3H8OS2)] as it is contraindicated or ineffective in poisoning from iron.

• Lager

  Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area away from light.

• läuterung methode

  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.
