In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H 3 PO 4. The phosphate or orthophosphate ion [PO 4] 3− is derived from phosphoric acid by the removal of three protons H +.
Branched polyphosphoric acids give similarly branched polyphosphate anions. The simplest example of this is triphosphono phosphate [OP(OPO 3) 3] 9− and its partially dissociated versions. The general formula for such (non-cyclic) polyphosphate anions, linear or branched, is [H n+2−k P n O 3n+1] k−, where the charge k may vary from 1 to n + 2.
Phosphate is an inorganic anion of phosphoric acid OP(OH) 3. There are also organophosphorus compounds with the formula OP(OR) 3. Subcategories.

The anion has an ethane-like structure and contains a P−P bond. The formal oxidation state of phosphorus is +4. The oxygen analogue is the hypodiphosphate anion, P 2 O 4− 6. P 3 S 3− 9 contains a six-membered P 3 S 3 ring. The ammonium salt is produced by reaction of P 4 S 10 in liquid ammonia. [13]

The formal list is used. The name of the most electronegative element is modified to end in -ide and the more electropositive elements name is left unchanged. Taking the binary compound of sodium and chlorine: chlorine is found first in the list so therefore comes last in the name. Other examples are PCl 5 phosphorus pentachloride
The model is defined in terms of a list of those complex species which are present in solutions in significant amounts. In the present context the complex species have the general formula [M p O q (OH) r] n±. where p, q and r define the stoichiometry of the species and n± gives the electrical charge of the ion. The experimental data are ...
