What is the reaction between sodium phosphate and sodium ...

The neutralization equations for phosphoric acid are: NaOH + H3PO4 > NaH2PO4 + H2O (aka monobasic sodium phosphate) NaOH + NaH2PO4 > Na2HPO4 + H2O (aka dibasic sodium phosphate) NaOH + Na2HPO4 > Na3PO4 + H2O (aka tribasic sodium phosphate) Of course, once all the hydrogen is consumed there is no further reaction with sodium hydroxide.
