1. Potassium react with red phosphorus.
3K + R = K3R.
2. Formation of phosphine during the reaction of water and potassium phosphine.
K3R + 3H2O = PH3 + 3KON.
3. Combustion of phosphine.
PH3 + O2 = P2O5 + H2O.
4. The reaction of phosphorus oxide with water – the formation of phosphoric acid.
P2O5 + 3H2O = 2H3PO4
