Phosphate can form many polymeric ions such as pyrophosphate, (P 2 O 7) 4−, and triphosphate, (P 3 O 10) 5−. The various metaphosphate ions (which are usually long linear polymers) have an empirical formula of (PO 3) − and are found in many compounds. Biochemistry of phosphates See more 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, aka. phosphoric acid H3PO4.
