H3PO4 – phosphoric acid
1) Reacts with bases
H3PO4 + 3NaOH = Na3PO4 + 3H2O
2) Reacts with basic oxides
2H3PO4 + 3CaO = Ca3 (PO4) 2 + 3H2O
3) Reacts with amphoteric oxides
2H3PO4 + 3ZnO = Zn3 (PO4) 2 + 3H2O
4) Reacts with salts
But with such a reaction, a precipitate must necessarily fall out or gas will be released, if there is no precipitate or gas, then the reaction cannot go
H3PO4 + 3KON = K3PO4 + 3H2O
5) Reacts with metals located in the line of activity to hydrogen
2H3PO4 + 3Ca = Ca3 (PO4) 2 + 3H2 ↑
