Phosphorus always occurs as the phosphate ion.
Large quantities are treated with water to make orthophosphoric acid (H3PO4), commonly called phosphoric acid, which has diverse industrial applications, including the production of phosphates, salts that contain the phosphate ion (PO43−), the hydrogen phosphate ion (HPO42−), or the dihydrogen phosphate ion (H2PO4−).
Another example is the secondary phosphate ion, HPO42−, which can either lose or accept a proton, according to the following equations: HPO42− ⇄ PO43− + H+ and HPO42− + H+ ⇄ H2PO4−.
Phosphorus is present in the fluids within cells of living tissues as the phosphate ion, PO43−, one of the most important mineral constituents for cellular activity.
A sugar (deoxyribose) and phosphate ion combine with one of four amino acids.
The estimated optimum pH of phosphate ion retention for the considered sorbents was 5.
The excimer emission has been used to confirm the selective recognition of phosphate ion.
A chiral phosphate ion plays a dual role, coaxing a fluorinating agent into solution and then catalyzing its reaction there.
First, phosphate anions such as the hydrogen phosphate ion (HPO4 2-) or the dihydrogen phosphate ion (H2PO4 -) in solution are preferentially adsorbed on noble metal single crystals, which can greatly disturb the growth of the plane [24].
Using NaH2PO4, a stable solution was prepared with high calcium and phosphate ion concentrations.
The pro-moiety is grafted via an ester function to CsA and the solubilizing group is a phosphate ion.
