2 NaHCO3 (aq) + CaCl2 (aq) → 2 NaCl (aq) + CaCO3 (s) + CO2 (g) + H2O (l)
This is a precipitation reaction: CaCO3 is the formed precipitate.
This is a gas evolution reaction, CO2 is the formed gas.
- NaHCO3 – Sodium hydrogen carbonate
- CaCl2 – Calcium chloride
- NaCl – Sodium chloride
- CaCO3 – Calcium carbonate
- H2O – Water, oxidane
