Write the reaction equations: P – P2O5 – H3PO4

Phosphorus is a non-metal that burns easily to form oxides. Let’s compose the equation of the phosphorus combustion reaction. The reaction product is phosphorus (V) oxide.

4P + 5O2 = 2P2O5.

Phosphorus (V) oxide is an acidic oxide. Acidic oxides react with water to form their corresponding acid. Phosphorus (V) oxide corresponds to phosphoric acid. Let’s compose the equation of the reaction between phosphorus oxide and water.

P2 O5 + 3 H2O = H3 PO4.
