Magnesium Nitrate Structure

Prominent Reactions of Mg(NO3)2

A chemical reaction between magnesium nitrate and sodium carbonate produces magnesium carbonate and sodium nitrate [7].

Mg(NO3)2 Na2CO3 = MgCO3 2NaNO3

Magnesium nitrate decomposes in water forming magnesium hydroxide, ammonia and oxygen [8].

Mg(NO3)2 4H2O = Mg(OH)2 2NH3 4O2

On heating Mg(NO3)2, it decomposes in magnesium oxide, nitrogen dioxide and oxygen [9].

2Mg(NO3)2 = 2MgO 4NO2 O2

It reacts with sodium hydroxide to give magnesium hydroxide and sodium nitrate [10].

Mg(NO3)2 2NaOH = Mg(OH)2 2NaNO3

Magnesium Nitrate Uses

  1. As a safe source of nitrate ions [4].
  2. In the production of nitrogenous fertilizers [4].
  3. In pyrotechnics and concentrated nitric acid manufacture [6].
  4. Helps in prilling and coating for ammonium nitrate production and is an ingredient of cosmetics and shampoos [6].

Is It Dangerous

Being a strong oxidizer, it may cause a fire hazard. It may also cause an explosion hazard when brought in contact with organic substances. Contact with eyes, skin and inhalation should be avoided as it results in irritation, coughing and shortness of breath. Ingestion in large quantities results in abdominal pain, dizziness, bloody diarrhea, vomiting, convulsions, weakness and collapse [6].
