    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].

    ??? ??

    Magnesium nitrate is white crystalline solid.

    ??? ??

    White crystals.Soluble in water and alcohol; deliquescent.

    ??

    In pyrotechnics; in the concentration of nitric acid.

    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.

    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.

    ???

    Dangerous fire and explosion risk in contact with organic materials, strong oxidizing agent.

    ????

    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.

    ??? ??

    Magnesium nitrate is used in fireworks and in the production of concentrated nitric acid.
