Magnesium nitrate Chemical Properties,Uses,Production
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.
Uses
In pyrotechnics; in the concentration of nitric acid.
Preparation
The magnesium nitrate used in commerce has been synthesized in a variety of ways. The reaction between nitric acid and magnesium metal is one way and reaction with MgO is another. Magnesium hydroxide and ammonium nitrate also form the product but ammonia is released as a by-product:
2HNO3 + Mg Mg(NO3)2 +H2
2HNO3 + MgO Mg(NO3)2 +H2O
Mg(OH)2 + 2NH4NO3 Mg(NO3)2 + 2NH3 + 2H2O
Since magnesium nitrate has a high affinity for water, heating the hexahydrate does not result in the dehydration of the salt. Instead, it decomposes into magnesium oxide, oxygen and nitrogen oxides:
4Mg(NO3)2·6H2O + heat 4MgO + 2NO2 + 2N2O + O2 + 6H2O
Heating the hexahydrate above its melting point first forms basic nitrates, such as Mg(NO3)2·4Mg(OH)2. It is this salt that decomposes at 400 C, forming magnesium oxide and oxides of nitrogen. The absorption of these nitrogen oxides in water is one possible way to synthesize HNO3. Although it is inefficient, it does not require the use of another strong acid and the mineral, nitromagnesite, can be used in this context.
Definition
ChEBI: The inorganic nitrate salt of magnesium.
General Description
A white crystalline solid. Produces toxic oxides of nitrogen if heated to decomposition. Used in pyrotechnics.
Air & Water Reactions
Deliquescent. Water soluble.
Reactivity Profile
Mixtures of Magnesium nitrate 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 has been reported to undergo spontaneous decomposition in dimethylformamide [Bretherick 5th ed., 1995]. Magnesium nitrate tends to behave as a strong oxidizer.
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.
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. See also NITRATES and MAGNESIUM COMPOUNDS.
Potential Exposure
Magnesium nitrate is used in fireworks and in the production of concentrated nitric acid.
Shipping
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
