- NaCl

HCl + NaOH → NaCl + H₂O

Na + Cl → NaCl

- Na₂CO₃

H₂CO₃ + 2NaOH → Na₂CO₃ + 2H₂O

Na₂O + H₂CO₃ → Na₂CO₃ + H₂O

Na + H₂CO₃ → Na₂CO₃ + H₂

2NaOH +CO₂ → Na₂CO₃ + H₂O

CaCO₃ + 2NaCl → Na₂CO₃ + CaCl₂

2NaOHCO₃ → Na₂CO₃ + H₂O + CO₂

- NH₄Cl

HCl + NH₃ → NH₄Cl

NaCl + NH₄HCO₃ → NH₄Cl +NaHCO₃

NaCl + (NH₄)₂SO₄ + 2NaCl → NH₄Cl +Na₂SO₄

-Al₂(SO₄)₃

3H₂SO₄ + Al₂SO₃ → Al₂(SO₄)₃ + 3H₂O
