Chemical Properties
Mercuric nitrate is a white to yellowish crystalline solid with an odor like nitric acid. Normally exists
as the hemihydrate or the dihydrate
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.
Hazard
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.
Shipping
UN1625 Mercuric nitrate, Hazard Class: 6.1;
Labels: 6.1-Poisonous materials.
Incompatibilities
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)

storage
Color Code—Blue: Health Hazard/Poison: Store in a secure poison location. Prior to working with this chemical you should be trained on its proper handling and storage. Mercuric nitrate must be stored to avoid contact with organic materials; acetylene, ethanol, phosphine, sulfur, and hypophosphoric acid, since violent reactions occur. See also “Incompatibilities.” Do not store on wooden floors.
