Na2H2P2O7
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.
Na4P2O7
The IUPAC name is disodium dihydrogen diphosphate, althogh this is not widely used. As a food additive it is normally called sodium acid pyrophosphate, SAPP, or by its E number, E450
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]."
Sodium caseinate, also called casein, is vegetarian but not vegan.
It can be. You can have a low sodium vegan diet.
Disodium pyrophoshate refers to Sodium Dihydrogen Pyrophosphate. Its formuyla is Na2H2P2O7
It is not an acid it is sodium salt of ethanoic acid.

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.
It is French for pyrophosphate disodium.
