NaH2PO4 I believe
This is the formula for disodium hydrogen phosphate dodecahydrate.
Those are chemical formulas. NH4 is the ammonium polyatomic ion, and PO4 is the phosphate polyatomic ion. Ammonium has a +1 charge and phosphate has a -3 charge.
sodium is Na phosphate is PO43- again, if you meant to ask the formula of the compound sodium phosphate it is Na3PO4
The formula is NaH2PO4.
NaH2PO4
The chemical formula for sodium phosphate is Na3PO4.
The chemical formula for sodium acid phosphate is NaH2PO4.
The chemical formula for disodium phosphate is Na2HPO4.
The compound with formula Na3PO4 is named "sodium phosphate", "trisodium phosphate", "sodium ortho-phosphate", or "trisodium ortho-phosphate".
Sodium phosphate, usually listed as an ingredient on food labels, can be referring to either monosodium phosphate, disodium phosphate, or trisodium phosphate. It is usually an emulsifier (thickener) or a preserving agent. Disodium is the one most commonly used.
NaH2PO4 * 7H2O
Na2HPO4, also known as disodium hydrogen phosphate, is a sodium salt commonly used in the chemical industry and as a buffering agent in the laboratory. It is a white, crystalline solid that is soluble in water and has various applications in food processing, water treatment, and as a pH regulator.
