Write the reaction equation: Na → Na2O2 → Na2O → NaOH → Na3PO4 → NaNO3. Indicate the types of reactions. Na2CO3 5 write the reaction in abbreviated ionic form.

1) Sodium peroxide is formed by the combustion of sodium in oxygen:
2Na + O -> Na2O2 – compound reaction
2) Calcining sodium peroxide with excess sodium will help to obtain sodium oxide:
Na2O2 + 2Na -> 2Na2O – compound reaction
3) Interacting with water, sodium oxide forms an alkali – sodium hydroxide:
Na2O + H2O -> 2NaOH – compound reaction
4) Interacting with an acid, sodium hydroxide forms sodium orthophosphate:
3NaOH + H3PO4 -> Na3PO4 + 3H2O – exchange reaction
5) The interaction of sodium orthophosphate and silver nitrate forms sodium nitrate:
Na3PO4 + 3AgNO3 -> 3NaNO3 + Ag3PO4 ↓ – exchange reaction
3Na + + PO42- + 3Ag + + 3NO3- -> 3Na + + 3NO3- + Ag3PO4 ↓
PO42- + 3Ag + -> Ag3PO4 ↓ – abbreviated ionic form of the 5th formula.
