Шаблон:About Шаблон:Chembox

Dimagnesium phosphate is a compound with formula MgHPO4. It is a Mg2+ salt of monohydrogen phosphate. The trihydrate is well known, occurring as a mineral.[1]

It can be formed by reaction of stoichiometric quantities of magnesium oxide with phosphoric acid.

MgO + H3PO4 → MgHPO4 + H2O

Dissolving monomagnesium phosphate in water, forms phosphoric acid and depositing a solid precipitate of dimagnesium phosphate trihydrate:

Mg(H2PO4)2 + 3 H2O → Mg(HPO4).3H2O + H3PO4

The compound is used as a nutritional supplement, especially for infants and athletes. Its E number is E343.[2]
