Write the equations of chemical reactions P-P2O5 -H3PO4 -Na3PO4
| June 15, 2021 | education
Let us write down the solution of the transformation chain for inorganic substances:
Phosphorus – phosphorus oxide (5) – phosphoric acid – sodium phosphate
4P + 5O2 = 2P2O5 – compounds, phosphorus oxide (phosphoric anhydride) was obtained;
P2O5 + 3H2O = 2H3PO4 – phosphoric acid was formed during the compound;
Н3PO4 + 3NaOH = Na3PO4 + 3H2O – exchange, sodium phosphate is released.
The solution process confirms the connection of non-metals, oxides, acids, salts.
The end product is used in agriculture as a mineral fertilizer.
