The current model consists of 1,110 non-hydrogen atoms, 18 water molecules and 4 phosphate ions.

Plant roots alone may be incapable of taking up phosphate ions that are immobilized, for example, in soils with a pH.

The phosphate ion does not remain in the blood but is excreted through the urine.

Therefore, three sodium ions are needed to balance the charge of one phosphate ion.

A simple Qualitative method to determine the presence of phosphate ions in a sample is as follows.

For example, the phosphate ion can be successively protonated to form phosphoric acid.

For example, the phosphate ion containing radioactive phosphorus-32 is PO.

A phosphate ion is lost into solution.

The glass surface has a negative charge due to adsorbed phosphate ions.

For example, 12-Phosphotungstic acid is formed by condensing phosphate ion with tungstate ions.
