Description

Ferric nitrate is a pale violet, green, or grayish-white, odorless solid in lumpy crystals (like salt).Molecular weight = 241.88; Boiling point = decomposes;Freezing/Melting point = 35 C; 47 C (nonhydrate). Hazard Identification (based on NFPA-704 M Rating System):Health 2, Flammability 1, Reactivity 3, Oxidizer. Highlysoluble in water.

Chemical properties

Violet crystals. Soluble in water and alcohol.

Chemical properties

Ferric nitrate is a pale violet, green, or grayish-white, odorless solid in lumpy crystals (like salt).

Physical properties

The nonahydrate form occurs as grayish-violet crystal; density 1.68 g/cm³; hygroscopic; decomposes at 47°C; very soluble in water, alcohol and acetone.

The Uses of Ferric nitrate

Dyeing (mordant for buffs and blacks), tanning, analytical chemistry.

General Description

A violet crystalline solid. Noncombustible but Ferric nitrate will accelerate the burning of combustible materials. If large quantities are involved in the fire or the combustible material is finely divided an explosion may result. Prolonged exposure of the material to fire or heat may result in an explosion. Toxic oxides of nitrogen are produced in fires involving Ferric nitrate. Ferric nitrate is used for dyeing and tanning, in chemical analysis, and in medicine.It is a strong oxidant and irritant,and a fire hazard when in contact with organic substances.

Air & Water Reactions

Soluble in water.

Reactivity Profile

Ferric nitrate is an oxidizing agent. Mixtures with alkyl esters may explode, owing to the formation of alkyl nitrates. Mixtures with phosphorus, tin(II) chloride or other reducing agents may react explosively [Bretherick, 1979 p. 108-109].

Hazard

Dangerous fire risk in contact with organic materials. Strong oxidant and irritant.

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.

Safety Profile

Mutation data reported.A reactive oxidizer.

Potential Exposure

Ferric nitrate is used in textile dyeing, tanning, and weighting silk.

First aid

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. Seek medical 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. The symptoms of metal fume fevermay be delayed for 4-12 h following exposure: it may lastless than 36 h.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.

storage

Color Code—Yellow: Reactive Hazard; Store in alocation separate from other materials, especially flammables and combustibles. Prior to working with this chemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area away from organic materials and other combustible materials or aluminum powder. See OSHAStandard 1910.104 and NFPA 43A Code for the Storage ofLiquid and Solid Oxidizers for detailed handling and storageregulations.

Shipping

UN1466 Ferric nitrate, Hazard Class: 5.1; Labels: 5.1-Oxidizer.

Incompatibilities

An oxidizer. Keep away from reducing agents, oxidizable materials and combustibles including metal powders, sulfur, and organic materials, combustibles,and easily oxidizable materials. Light sensitive. Aqueous solution is corrosive to metals.
