Magnesium phosphate is a general term for salts of magnesium and phosphate appearing in several forms and several hydrates: [1] Monomagnesium phosphate (Mg(H 2 PO 4) 2). xH 2 O; Dimagnesium phosphate (MgHPO 4). xH 2 O; Trimagnesium phosphate (Mg 3 (PO 4) 2). xH 2 O; Amorphous magnesium phosphate is also claimed. [2] Trimagnesium phosphate.
Monomagnesium phosphate is one of the forms of magnesium phosphate. It is a magnesium acid salt of phosphoric acid with the chemical formula Mg(H 2 PO 4) 2. Di- and tetrahydrates are known also. It dissolves in water, forming phosphoric acid and depositing a solid precipitate of Mg(HPO 4). 3H 2 O, dimagnesium phosphate. [2]
Trimagnesium phosphate describes inorganic compounds with formula Mg 3 (PO 4) 2. xH 2 O. They are magnesium acid salts of phosphoric acid, with varying amounts of water of crystallization: x = 0, 5, 8, 22. [2] The octahydrate forms upon reaction of stoichiometric quantities of monomagnesium phosphate (tetrahydrate) with magnesium hydroxide.
Magnesium salts are included in various foods, fertilizers (magnesium is a component of chlorophyll), and microbe culture media. Magnesium sulfite is used in the manufacture of paper (sulfite process). Magnesium phosphate is used to fireproof wood used in construction. Magnesium hexafluorosilicate is used for moth-proofing textiles.

Dimagnesium phosphate is a compound with formula MgHPO 4. It is a Mg 2+ 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 + H 3 PO 4 → MgHPO 4 + H 2 O

The pyrophosphate anion has the structure P 2 O 4− 7, and is an acid anhydride of phosphate. It is unstable in aqueous solution and hydrolyzes into inorganic phosphate: P 2 O 4− 7 + H 2 O → 2 HPO 2− 4. or in biologists' shorthand notation: PP i + H 2 O → 2 P i + 2 H +
