Phosphate Anhydrous

Dicalcium phosphate, also known as calcium monohydrogen phosphate, is a dibasic calcium phosphate. It is usually found as the dihydrate, with the chemical formula of CaHPO4
• 2H2O, but it can be thermally converted to the anhydrous form. It is practically insoluble in water, with a solubility of 0.02 g per 100 mL at 25 °C.

Disodium hydrogen phosphate (Na2HPO4) is a sodium salt of phosphoric acid. It is a white powder that is highly hygroscopic and water soluble.[1] It is therefore used commercially as an anti-caking additive in powdered products. It is also known as disodium hydrogen orthophosphate, sodium hydrogen phosphate or sodium phosphate dibasic.

Monosodium phosphate (NaH2PO4), also known as anhydrous monobasic sodium phosphate is a chemical compound of sodium with a phosphate counterion. It is used as a laxative and, in combination with other sodium phosphates, as a pH buffer.

Sodium tripolyphosphate (STPP, sometimes STP or sodium triphosphate or TPP[1]), with formula Na5P3O10, is a polyphosphate of sodium. It is the sodium salt of triphosphoric acid.

Tricalcium phosphate is a compound with formula Ca3(PO4)2. It is also known as calcium orthophosphate, tertiary calcium phosphate, tribasic calcium phosphate, or "bone ash" (calcium phosphate being one of the main combustion products of bone).

Trisodium phosphate (TSP) is a cleaning agent, food additive, stain remover and degreaser. It is a white, granular or crystalline solid, highly soluble in water producing an alkaline solution. The item of commerce is often partially hydrated and may range from anhydrous trisodium phosphate, Na3PO4, to the dodecahydrate, Na3PO4·12H2O.
