What is Magnesium Phosphate?
Magnesium Phosphate, Mg3(PO4)2 is an important mineral found in bones, in the seeds of many plants, and in a number of minerals. It is taken as a source of supplemental dietary magnesium. Tribasic magnesium phosphate may be prepared by the interaction of magnesium chloride or sulphate with the phosphate salt. The solution is easily prepared by agitating some salt with carbon dioxide-free water for several hours.
Other names – Trimagnesium diphosphate, Phosphoric acid magnesium salt

Chemical Properties of Magnesium Phosphate – Mg3(PO4)2
-
- Magnesium Phosphate is a salt when treated with water forms phosphoric acid and magnesium hydroxide. The chemical equation is given below.
Mg3(PO4)2 + 6H2O → 2H3PO4 + 3Mg(OH)2
-
- Magnesium Phosphate reacts with hydrochloric acid forms phosphoric acid and magnesium chloride.
Mg3(PO4)2 + 6HCl → 3MgCl2 + 2H3PO4
