1.As a result of the reaction between phosphoric acid and sodium oxide, sodium phosphate and water are formed.

2H3PO4 + 3 Na2O = 2Na3PO4 + 3H2O.

2.The reaction between phosphoric acid and magnesium oxide produces magnesium phosphate and water.

2H3PO4 + 3MgO = Mg 3 (PO4) 2 + 3H2O.

3.The reaction between phosphoric acid and lithium oxide produces lithium phosphate and water.

2H3PO4 +3 Li2O = 2 Li3PO4 + 3H2O.

4.As a result of the reaction between phosphoric acid and calcium oxide, calcium phosphate and water are formed.

2H3PO4 + 3CaO = Ca3 (PO4) 2 + 3H2O.
