2Na + H₂ = 2NaH
NaH + H₂O = NaOH + H₂
3NaOH + H₃PO₄ = Na₃PO₄ +3H₂O
2Na₃PO₄ + H₃PO₄ = 3Na₂HPO₄
Na₂HPO₄+NaOH = Na₃PO₄ + H₂O
Na₃PO₄ + AlCl₃ = 3NaCl + AlPO₄
2NaCl (электролиз расплава) 2Na + Cl₂
2Na + O₂ = Na₂O₂
Na₂O₂+2Na=2Na₂O
Na₂O+CO₂=Na₂CO₃
Na₂CO₃+H₂O+CO₂=2NaHCO₃
NaHCO₃+NaOH = Na₂CO₃+H₂O
Na₂CO₃+Ba(OH)₂ = 2NaOH + BaCO₃
2NaOH +H₂SO₄ = Na₂SO₄ +2H₂O
Na₂SO₄+BaBr₂=2NaBr+BaSO₄
