Na2HPO4
Thank hangtimepro for that one.
Sodium Acid Phosphate B.P. has the formula NaH2PO4.2H2O. There is also a monohydrate (1H2O)
Na2HPO4
Na3po4
Sodium Tri(poly)phosphate = Na5P3O10
Na3PO4
Sodium has a single positive charge (+), whilst phosphate ions have a 3- charge. To balance out the charges, three sodium ions are needed, so the formula will be Na3PO4.
98g of phosphoric acid require 120g of sodium hydroxide to produce sodium phosphate so 150g phosphoric acid will require = 120/98x150= 183.67g sodium hydroxide.
Sodium Phosphate
The formula for sodium phosphate tribasic is Na3PO4
sodium is Na phosphate is PO43- again, if you meant to ask the formula of the compound sodium phosphate it is Na3PO4
The compound with formula Na3PO4 is named "sodium phosphate", "trisodium phosphate", "sodium ortho-phosphate", or "trisodium ortho-phosphate".
Examples: calcium phosphate, sodium phosphate, potassium phosphate, uranyl phosphate.
Sodium Tri(poly)phosphate = Na5P3O10
The formula is NaH2PO4.
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.

Combine phosphoric acid and sodium hydroxide, very carefully, this will leave you with what you can utilise as sodium phosphate.
