Which of the listed substances interacts with phosphorus (V) oxide: 1) sulfur (IV) oxide; 2) sodium hydroxide; 3) oxygen; 4) sulfuric acid.
Phosphorus (V) oxide P2O5 will react with sodium hydroxide NaOH.
The equations of their interaction at various ratios of oxide and alkali are as follows:
6NaOH + P2O5 = 2Na3PO4 + 3H2O (sodium orthophosphate and water are formed).
4NaOH + P2O5 = 2Na2HPO4 + H2O (sodium phosphate and water are formed).
