Magnesium nitrite represented by the chemical formula Mg(NO2)2 or MgN2O4 that bears the IUPAC name magnesium dinitride  is a white powder at room temperature that is soluble in water and alcohol [3, 4]. It is a magnesium salt and an ionic compound . It should be protected from moisture to prevent it from decomposing .
Magnesium Nitrite Identification
|CAS Number||15070-34-5 |
|PubChem CID||10197667 |
|ChemSpider ID||8373167 |
How to Make It
Magnesium nitrite can be prepared by reacting magnesium hydroxide with nitrous acid .
Mg(OH)2 + 2HNO2 = Mg(NO2)2 + 2H2O
It can also be made by a reaction between cobalt nitrite and magnesium .
Co(NO2)2 + Mg = Mg(NO2)2 + Co
