Na3PO4 raises the boiling point of water the most the name for that element is Sodium Phosphate the equation of Sodium Phosphate is Na3PO4 and the type of reaction is a decomposition reaction because it decomposes of Sodium (Na) and Phosphate (PO4). if you are looking for the balanced equation it is easy Na + PO4= Na3PO4
to balance the equation you put a three in front of the Na and your equation is now balanced
