P4O6 reacts with water to give phosphoric acid. The chemical name of P4O6 is Phosphorus trioxide.
It is formed by burning phosphorus in the limited supply of oxygen.
The reaction is as follows:
P4 + 3O2 → P4O6
This product reacts with water and forms phosphorus acid. The chemical formula of phosphoric acid is H3PO3
The reaction occurs as follows: P4O6 + 6H2O → 4H3PO3
