Sodium phosphate is a generic term for the salts of sodium and phosphate. They are:
Monosodium phosphate (NaH2PO4), Disodium phosphate (Na2HPO4) and Trisodium phosphate (Na3PO4).
Sodium phosphates are used as food additives, used as an acidity regulator (buffering agent), emulsifier, thickening agent, nutrition enlargement agent and sequestrant (metal-chelating agent).
Sodium phosphates are added to many foods as an emulsifier to prevent oil separation, such as processed cheeses, processed meats, ready-made meals and tinned (canned) soups. Sodium phosphates are also commonly added to powdered soups, boullions and gravy mixtures.
Sodium phosphates can also be used as a leavening agent in foods, such as the batter coating on breaded fish or chicken, and commercially baked cakes.
Adding sodium phosphates to food increases the shelf life of the food; maintaining the texture and appearance of the food.

Monosodium phosphate (MSP)

CAS No: 7558-80-7 (anhydrous) 13472-35-0 (dihydrate)
Chemical Name: sodium dihydrogen phosphate
Molecular Formula: NaH2 PO4?XH2O(X=0,2)
Molecular Weight: 119.98 / 155.99
Chemical Structural:

Disodium phosphate (DSP)

CAS No: 7558-79-4 (anhydrous)
10028-24-7 (dihydrate)
7782-85-6 (heptahydrate)
10039-32-4 (dodecahydrate)
Chemical Name: disodium hydrogen phosphate
Molecular Formula: Na2 HPO4?XH2O(X=0,2,7,12)
Molecular Weight: 141.96 / 177.98 / 268.07 / 358.14
Chemical Structural:

Disodium phosphate is highly hygroscopic and water soluble. It is therefore used commercially as an anti-caking additive in powdered products.

Trisodium phosphate (TSP)

CAS No: 7601-54-9 (anhydrous)
10101-89-0 (dodecahydrate)
Chemical Name: ---
Molecular Formula: Na3PO4 ? XH2O (X=0,12)
Molecular Weight: 163.94 / 380.14
Chemical Structural:

Trisodium phosphate is generally found in hydrated forms. It is a highly water-soluble ionic salt. Solutions of it dissolved in water have an alkaline pH.
