orthophosphate's Usage Examples:

They may be obtained by heating a monometallic orthophosphate of a fixed base, or a dimetallic orthophosphate of one fixed and one volatile base, e.

Other names: Calcium hydrogen orthophosphate, calcium phosphate dibasic.

All soluble pyrophosphates when boiled with water for a long time are converted into orthophosphates.

Of the acid orthophosphates, the mono-calcium salt, CaH4(P04)2, may be obtained as crystalline scales, containing one molecule of water, by evaporating a solution of the normal salt in hydrochloric or nitric acid.

orthophosphate concentration must be maintained and stabilized as far as practical within the distribution system.

Of the calcium orthophosphates, the normal salt, Ca3(P04)2, is the most important.

microcosmic salt: MH 2 PO 4 MP0 3 +H 2 0, (NH 4) NaHPO 4 NaP03+NH3+H20; they may also be obtained by acting with phosphorus pentoxide on trimetallic orthophosphates: Na3P04+P205 3NaP0 3.

All soluble orthophosphates give with silver nitrate a characteristic yellow precipitate of silver phosphate, Ag 3 PO 4, soluble in ammonia and in nitric acid.

On boiling their solutions they yield orthophosphates, whilst those of the heavy metals on boiling with water give a trimetallic orthophosphate and orthophosphoric acid: 3AgP0 3 +3H 2 OAg 3 PO 4 +2H 3 PO 4.

The most important is the normal salt, Na 4 P 2 0 7, which is readily obtained by heating disodium orthophosphate, Na 2 HPO 4.

On heating with an oxide or carbonate they yield a trimetallic orthophosphate, carbon dioxide being evolved in the latter case.

orthophosphate dose will be higher in water with a high organic color content than in waters with a low organic color content.
