Magnesium Nitrate, Formula, Chemical Properties, Preparation, Uses

Magnesium Nitrate

Magnesium nitrate  is an inorganic compound forms the hydrates when it is present in the air. It is in the hygrocopic solid at the anhydrous form. It occurs naturally abundant in the nature. Being highly soluble in the water. the electrons are freely shared their energy to the other chemical compounds. The magnesium acts as the cations and the nitrate acts as the anions.The systematic IUPAC name is known as magnesium nitrate . The chemical or molecular formula of magnesium nitrate is Mg(NO3)2. It is also known as  magnesium dinitrate.

Structural formula

This is the structural formula of the magnesium nitrate:

Magnesium Nitrate

Chemical Formula

The chemical formula of the magnesium nitrate is Mg(NO3)2.

Preparation Method

When the magnesium hydroxide is reacted with the sodium nitrate it forms the magnesium nitrate is the product and sodium hydroxide is the byproduct. It is a strong acid and it absorbs the nitrogen oxides in the present of air. It can be synthesized only by the use of nitric acid. At the deliquescent water powder it looks like a white crystalline solid. The chemical reaction is given as below.

Chemical Properties

Magnesium nitrate is a non inflammable substances. if the solubility of water is increased, the temperature will be also increased. It is moderately soluble in ethanol and ammonia. The reaction is taken not easily and stable in nature. It looks like a white crystalline solid in the appearance. It is cubic in structure.

Uses

Magnesium nitrate is manufacturing the fertilizers for the plant growth. It controls the pesticides when it sprays on the plant. It acts as a dehydrating agent for preparing the concentrated nitric acid. Naturally it is found in the caverns and mines.
