Na4P2O7
Na2H2P2O7
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.
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 can also be called disodium pyrophosphate, but it doesn't have a more common name. It can be one of the ingredients of baking powder.

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).
Iron pyrophosphate is a chemical compound with the formula Fe4(P2O7)3. It is commonly used as a food additive to fortify foods with iron. Iron pyrophosphate is also used in various industrial applications such as in paints and coatings.
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.
It is French for pyrophosphate disodium.
