5.1 | [Safety Profile]
Probably a severe
irritant to the eyes, skin, and mucous
membranes. A powerful oxidizer. Violent
decomposition on contact with
dmethylformamide. When heated to
decomposition it emits toxic fumes of NOx.

| Hazard Information | Back Directory | [General Description]
A white crystalline solid. Produces toxic oxides of nitrogen if heated to decomposition. Used in pyrotechnics. | [Reactivity Profile]
Mixtures of MAGNESIUM NITRATE(10377-60-3) 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]. Noncombustible but 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. Prolonged exposure to fire or heat may result in an explosion. MAGNESIUM NITRATE(10377-60-3) has been reported to undergo spontaneous decomposition in dimethylformamide [Bretherick 5th ed., 1995]. MAGNESIUM NITRATE(10377-60-3) tends to behave as a strong oxidizer. | [Air & Water Reactions]
Deliquescent. Water soluble. | [Hazard]
Dangerous fire and explosion risk in contact
with organic materials, strong oxidizing agent. | [Health Hazard]
Exposure can cause mild irritation to the mucous membranes. Symptoms may include coughing and shortness of breath. Ingestion of large doses may cause dizziness, abdominal pain, vomiting, bloody diarrhea, weakness, convulsions, and collapse. Contact with skin may cause irritation, redness, and pain. | [Potential Exposure]
Magnesium nitrate is used in fireworks and in the production of concentrated nitric acid. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions,
including resuscitation mask) if breathing has stopped and
CPR if heart action has stopped. Transfer promptly to a
medical facility. When this chemical has been swallowed,
get medical attention. Give large quantities of water
and induce vomiting. Do not make an unconscious person
vomit

UN1474 Magnesium nitrate, Hazard Class: 5.1;
Labels: 5.1-Oxidizer | [Incompatibilities]
A powerful oxidizer. Violent reaction
with dimethylformamide, reducing agents; combustibles,
fuels, organic and easily oxidizable matter | [Description]
Magnesium nitrate has the molecular formula of
Mg(NO3)2 and the molecular weight of 148.3152 g/
mol.
Magnesium nitrate is prepared by the action of nitric
acid on magnesium carbonate, oxide or hydroxide:
MgCO3 + 2HNO3 ? Mg(NO3)2 + CO2 +H2O
Mg(OH)2 + 2HNO3 ? Mg(NO3)2 + 2H2O
The salt crystallizing at room temperature after
evaporation is the hexahydrate, Mg(NO3)2·6H2O. Two
stable hydrates are formed, the hexahydrate [CAS
number =13446-18-9] and the dihydrate, Mg(NO3)2·
2H2O [CAS number = 15750-45-5]. | [Chemical Properties]
Magnesium nitrate is white crystalline solid. | [Chemical Properties]
White crystals.Soluble in water and alcohol;
deliquescent. | [Uses]
In pyrotechnics; in the concentration of nitric acid. | [Uses]
It is used in printing, chemical, agriculture and ceramics industries. Its fertilizer grade has 10.5% nitrogen and 9.4% magnesium. | [Definition]
ChEBI: The inorganic nitrate salt of magnesium. | [Flammability and Explosibility]
Nonflammable | [storage]
Color Code—Yellow: Reactive Hazard (strongoxidizer); Store in a location separate from other materials,especially flammables and combustibles. Prior to workingwith this chemical you should be trained on its proper handling and storage. Magnesium nitrate must be stored toavoid contact with dimethyl formamide, fuels, and strongreducing agents, since violent reactions occur. Store intightly closed containers in a cool, well-ventilated areaaway from flammable and combustible materials. Avoidstorage on wood floors. See OSHA Standard 1910.104 andNFPA 43A Code for the Storage of Liquid and SolidOxidizers for detailed handling and storage regulations. |
| Questions And Answer | Back Directory | [Physical Properties]
The anhydrous salt consists of white cubic crystals; density 2.3 g/cm3; very soluble in water. The dihydrate is white crystalline solid having density 1.45 g/cm3; decomposes at about 100°C; soluble in water and ethanol. The hexahydrate, MgNO3•6H2O is a colorless solid having monoclinic crystal structure and density 1.46 g/cm3. The salt is hygroscopic and very soluble in water and moderately soluble in ethanol.
| [Occurrence and Uses]
The hexahydrate, Mg(NO3)2•6H2O, occurs in nature as mineral nitromagnesite. Magnesium nitrate is used in pyrotechnics; and in the manufacture of concentrated nitric acid to remove water and concentrate the acid vapors to 90–95% HNO3. It also is used to aid coating and prilling in production of ammonium nitrate. The salt also is used as an analytical standard for magnesium and a matrix modifier in furnace atomic absorption spectroscopic analysis. It also finds some limited application as a nitrogenous fertilizer.
| [Preparation]
Magnesium nitrate is prepared by the action of nitric acid on magnesium carbonate, oxide or hydroxide:
MgCO3 + 2HNO3 → Mg(NO3)2 + CO2 + H2O
Mg(OH)2 + 2HNO3 → Mg(NO3)2 + 2H2O
The salt crystallizing at room temperature after evaporation is the hexahydrate, Mg(NO3)2•2H2O.
| [Reactions]
Thermal decomposition of anhydrous Mg(NO3)2 yields magnesium oxide and nitrogen oxides. Heating the hexahydrate above its melting point forms basic nitrates, such as Mg(NO3)2•4 Mg(OH)2. The latter decomposes at 400°C, forming magnesium oxide and oxides of nitrogen. Magnesium nitrate forms addition compounds with a number of nitrogen-containing organics such as pyridine, aniline, and urea.
