Pyrophosphate has the chemical formula (P2O7)-4. It is a class of chemical anions that were originally formed from heating (pyro) phosphates. They are formed by esterification of two phosphates (linking them with one of the phosphate oxygen atoms).
Disodium pyrophoshate refers to Sodium Dihydrogen Pyrophosphate. Its formuyla is Na2H2P2O7
The chemical formula of tetrasodium pyrophosphate is: Na4P2O7. The structural formula is: (P surrounded by 4 oxygen atoms)-(bonding at a common O)-(to another P surrounded by 4 oxygen atoms), yielding the pyrophosphate ion. 4 sodium ions (Na+) bind to that complex via ionic bonds.
Zinc pyrophosphate is typical. It's chemical formula is Zn2P2O7. Ignoring the zinc then, Zn, pyrophosphate consists of phosphorus, P, and oxygen, O. Please see the link.

Fe3+ PO43- ----> these are the ions and their charges FePO4 ----> the charges have to add up to zero, so one +3 iron ion cancels out one -3 phosphate ion FePO4 -----> final formula
to keep mineral crystals from building up on the fish (sodium acid pyrophosphate). Sodium pyrophosphate is used as a buffering agent, an emulsifier, a dispersing agent, and a thickening agent, and is often used as a food additive. Common foods containing sodium pyrophosphate include chicken nuggets, marshmallows, pudding, crab meat, imitation crab, canned tuna, and soy-based meat alternatives. "Sodium pyrophosphate, also called tetrasodium pyrophosphate or tetrasodium phosphate, is a slightly toxic and mildly irritating colorless transparent crystalline chemical compound with the formula Na4P2O7 and CAS number 7722-88-5. It contains the pyrophosphate ion. Toxicity is approximately twice that of table salt when digested orally[1]."
It is French for pyrophosphate disodium.
