Magnesium Phosphate, Formula, Chemical Properties, Preparation, Uses

Magnesium Phosphate

Magnesium phosphate is an ionic compound that has consists of the combination of magnesium as the cation and phosphate as the anion. It is naturally found in the hydrated water. it can be crystallized through the amorphous forms. The magnesium phosphate consists the electrostatic force of attraction between the magnesium and phosphate. It appears as the white crystalline powder. The systematic IUPAC name is known as magnesium phosphate. The chemical or molecular formula of magnesium phosphate is Mg3(PO4)2.

Structural Formula

This is the structural formula of the magnesium phosphate is:

Magnesium Phosphate

Chemical Formula

The chemical formula of the magnesium phosphate is Mg3(PO4)2.

Preparation Method

When the tribasic orthophosphoric acid is reacted with the magnesium hydroxide in the laboratory by the process of neutralization. It gives the trimagnesium phosphate as the product and water as the byproduct.

2H3PO4+ 3Mg(OH)2 → Mg3(PO4)2 +6H2O

When this product is reacted with the hydrochloric acid it produces magnesium chloride salt and orthophosphoric acid. In the aqueous solution it can be prepared the dimagnesium phosphate dehydrate with the diacidic base is added.
