[Chemical Properties]

[Chemical Properties]

white to yellow crystalline powder with nitric acid odour
[General Description]

A white crystalline solid. Toxic by inhalation, ingestion and/or skin contact. Prolonged exposure to fire or heat may result in an explosion. Produces toxic oxides of nitrogen when heated to decomposition. Used to make other chemicals and in medicine.
[Reactivity Profile]

MERCURIC NITRATE(10045-94-0) is noncombustible, but, as an oxidizing agent, will accelerate the burning of combustible materials. If large quantities are involved in a fire or the combustible material is finely divided, an explosion may result. Light sensitive. 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]. Acetylene forms a sensitive acetylide when passed into an aqueous solution of MERCURIC NITRATE(10045-94-0) [Mellor 4:933. 1946-47]. Should not be mixed with alcohols as explosive mercury fulminates may be formed [Bahme 1961. p. 9]. Is violently reduced by hypophosphoric acid [Mellor 4:993. 1946-47]. Reacts with phosphine to give a yellow precipitate that explodes when heated or subjected to shock [Mellor 4:993. 1946-47].
[Air & Water Reactions]

Deliquescent. Soluble in a small amount of water. With much water or on boiling with water, an insoluble basic salt is formed.

Dangerous fire risk in contact with organic materials. Very toxic.
[Health Hazard]

Acute systemic poisoning may be fatal within a few minutes; death by uremic poisoning is usually delayed 5-12 days. Acute poisoning has resulted from inhaling dust concentrations of 1.2-8.5 mg/m 3 of air; symptoms inc lude tightness and pain in chest, coughing, and difficulty in breathing. Ingestion causes necrosis, pain, vomiting, and severe purging. Contact with eyes causes ulceration of conjunctiva and cornea. Contact with skin causes irritation and po ssible dermatitis; systemic poisoning can occur by absorption through skin.
[Potential Exposure]

Mercuric nitrate is used in making other chemicals; in felt manufacture and in making mercury fulminate
[First aid]

Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificia respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy. Antidotes and Special Procedures for authorized medical personnel: The drug NAP has been used to treat mercury poisoning, with mixed success.

UN1625 Mercuric nitrate, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

A strong oxidizer. Reacts violently with combustibles, petroleum hydrocarbons; reducing agents; aldehydes, ammonia, ketones, phosphorus. Reacts with acetylene, alcohol, phosphine, and sulfur to form shocksensitive compounds. Aqueous solution attacks most metals. Vigorous and dangerous reaction with petroleum hydrocarbons. Incompatible with organic materials; acetylene, ethanol, phosphine, sulfur, hypophosphoric acid. Inorganic mercury compounds are incompatible with acetylene, ammonia, chlorine dioxide; azides, calcium (amalgam formation), sodium carbide; lithium, rubidium, copper. Decomposes in heat or on exposure to light, producing toxic fumes (mercury, nitrogen oxides)

[PackingGroup ]

[Safety Profile]

Poison by ingestion, skin contact, intraperitoneal, and subcutaneous routes. A powerful oxidizer. Probably an eye, skin, and mucous membrane irritant. Reacts with acetylene to form the explosive mercury acetylide whch is sensitive to heat, friction, or contact with sulfuric acid. Reaction with ethanol forms the explosive mercury fulrmnate. Reaction with isobutene forms an unstable explosive product. Forms explosive mixtures with phosphine (heatand impact-sensitive), potassium cyanide (heat-sensitive), and sulfur. Violent reaction with phosphinic acid, hypophosphoric acid, unsaturated hydrocarbons, aromatics. Vigorous reaction with petroleum hydrocarbons. When heated to decomposition it emits very toxic fumes of Hg and NOx. See also MERCURY COMPOUNDS, INORGANIC; and NITRATES.
