- C*O₂ + H₂O ⇌ H₂CO₃
- CaO + CO₂ → CaCO₃
- NaOH + CO₂ → Na₂CO₃ + H₂O
- NaOH + CO₂ (excess) → Na₂CO₃ + H₂O
- Ca(OH)₂ + CO₂ → CaCO₃ + H₂O
- CaCO₃ + CO₂ (excess) + H₂O → Ca(HCO₃)₂
- CaCO₃ (s) → CaO + CO₂
- CaCO₃ + HCl → CaCl₂ + CO₂ + H₂O
- NaHCO₃ (s) → Na₂CO₃ + CO₂ + H₂O
- Ca(HCO₃)₂ → CaCO₃ + CO₂ + H₂O
- NaHCO₃ + NaOH → Na₂CO₃ + H₂O
- Ca(HCO₃)₂ + Ca(OH)₂ → 2CaCO₃ + 2H₂O
- NH₄HCO₃ → NH₃ + CO₂ + H₂O
- NaHCO₃ + H₂SO₄ → Na₂SO₄ + H₂O + CO₂
- Na₂CO₃ + H₂SO₄ → Na₂SO₄ + H₂O + CO₂
- NaHCO₃ + CH₃COOH → CH₃COONa + CO₂ + H₂O
