Formula for magnesium nitrite is 

Physical Properties:

Appearance: Typically white crystalline in appearance.

Solubility: Soluble in water, but with particular values related to temperature.

Melting Point: Magnesium nitrite decomposes before melting point. It typically melts between 100 °C (212 °F).

Density: Estimated value is around 1.24 g/cm³.

Molar Mass: Around 148.31 g/mol

Other Conditions

Magnesium nitrite is sometimes hygroscopic, this means it attracts moisture from the air.

It has many applications, most of which involve the use as a fertilizer and others include application in some chemical syntheses.

Chemical properties

Decomposition:

Magnesium nitrite decomposes into magnesium oxide, nitrogen dioxide, and oxygen on heating:

Magnesium nitrite + Heat → Magnesium oxide + Nitrogen dioxide + Oxygen

Reaction with Acids:

Magnesium nitrite reacts with acids to produce magnesium salts and give out nitrous acid

Magnesium nitrite+ Acid → Magnesium salt + Nitrous acid

Formation of Nitrous Oxide:

Nitrous oxide is formed by the reaction of magnesium nitrite with reducing agents.

Magnesium nitrite + Reducing agent → Nitrous oxide

Solubility:

It is soluble in water to form a solution of magnesium ions and nitrite ions which further can be used in further reactions.

Application

Fertilizer: Magnesium nitrite serves as a source of nitrogen in the fertilizers, which gives strength to the plant development and crop yield.

Corrosion Inhibitor: It is used in several industrial processes as a corrosion inhibitor of metal, particularly in cooling systems.

Chemical Synthesis: It is used as a reagent in organic synthesis to prepare hundreds of chemical compounds.

Food Preservation: It is sometimes used in food preservation techniques due to its antiseptic properties.

Laboratory application: Applied for the purposes of conducting research in compounds of nitrogen and their reactions.

Conclusion:

Magnesium nitrite is such a versatile compound that holds much significance in agriculture, industry, and laboratory research. The properties of this compound enable it as an effective fertilizer as a corrosion inhibitor besides acting as a reagent in chemical processes.
